There's significantly less money in it, though, and more hassle. It's not going to become popular enough until people get burned enough with vendors going out of business, or just stopping support, and making their convenient $199 gadgets obsolete.
In a sense, a large company like Nest pulling his off is a good thing: it sends the signal.
I can see a half dozen solidly practical uses for a smart home setup, mostly scheduling tasks to be done while I'm sleeping or not at home. Beyond that, I'd have a lot of fun just building silly hobby projects with cheap sensors, wifi-controlled lighting, etc. But I'm not going to touch any of it until I can get a system that's happy to run locally, and only calls out to the rest of the world when it actually needs to. At this point, I'm even going to hold out for adaptable integrations; if some service I'm talking to shuts down, I should be able to substitute another one honoring the same API. Anything less looks like a privacy, security, and ownership nightmare.
"the Internet of bricks" succintly conveys your first suggestion. "Internet of taps" for the second?
The most classical example of such “things” are softphones. They need their own vxlan and switch QOS policies and so forth, to function the way people expect phones to work (rather than flaking out when someone is torrenting.) Softphone deployments exist in plenty of enterprises, but have you ever heard of a SOHO deployment of softphones (where the phones are PBX extensions and can call each-other over the LAN; not where the phones are distinct phone-company DIDs sending IP packets through the gateway, out over the internet, and to the the phone company’s PBX terminus, just to talk to one-another)?
Until we get SOHO router-gateways smart enough to make such a SOHO softphone deployment “installation-free”, we’ll probably never see LANoT.
Running a RAID array was once as enterprisey as it gets. Now you can buy a RAID-ready box (something like Synology) and have a reasonable default configuration, or configure to your taste if you have a general knowledge of what you're doing.
I suppose that LANoT is going to develop eventually into something easy enough to deploy, too.
Re softphones: since US cable providers effectively sell softphones as a part of the cable package, they have every incentive to prevent home routers from allowing to easily set it up for free. OTOH the QoS settings are there in the routers firmwares for that same reason, and desktop / mobile softphones (aka "internet messengers") can use that if they care enough.
The tradeoff is that the quality is kind of bad and the ongoing fees comparatively high relative to IoT.
There's even the old DECT phones, if anyone's still using those.
(+ except where the internet companies have tried to break this by routing you through Hangouts or some other thing that isn't the phone system)
LIFX looks nice though. The UDP Lan protocol is really neat, and the documentation is better than I remember of Philips Hue.
While great advances come from availability of technology at a reduced up-front price, at what cost to the basic principles and advantages of ownership, privacy, cost depreciation, long term use of assets, etc. has our new world come?
This is a good reminder that “all magic, comes with a price”!
And really, that was the best case. Microsoft supported their legacy setup long after they stopped selling it, then finally offered refunds and support for importing playlists to Spotify. Newer, post-transformation services have dropped all pretense of guarantees or ownership; the Kindle Store revokes access to titles or whole collections so casually that the words "your library" are essentially a bad joke.
Even news has gone the same way. I had a very bad moment the first time I went to link someone to an article and found that the body had been completely rewritten with no editor's note (and not for correctness). News companies aren't profiting on the transition like music sellers did, but basic concepts like newspaper archives and the "paper of record" are thrown into doubt by the loss of ownership and content stability.
The story about farmers hacking back ownership of their tractors is surprising only because it's a bit ahead of the curve on hardware. We're still in the early days of this hardware-as-a-service transition, and it's going produce much uglier surprises than the ones we got with software.

The protagonist starts out by jail-breaking her toaster, which was designed on only toast authorized bread. However, the company that produced it went out of business (taken over by a hedge fund), and the authentication servers were shut down, so now the toaster couldn't toast anything.
Though I'd characterize "Someone Comes to Town, Someone Leaves Town" as superbly creepy.
Wish it was that simple.
With IoT, companies practicing dishonest and abusive business practices, like tying appliances to their SaaS and turning them from products into services, can get VC investment and simply outmarket the honest companies. Meanwhile, society develops antibodies slowly, so regular people are mostly unable to tell they're being taken advantage of (though cases like this help build this awareness). Consumers don't "vote with their wallets" for perfect solutions, they choose from what's on the market - and the market is saturated with bad actors right now.
As for games, it ain't easy either. Games are not commodities. The choice isn't between buying single player games requiring Internet connection and single player games not requiring it. The choice is between buying such Internet-tied games and not buying the next installment of your favorite franchise at all; between accepting abusive levels of DRM and the fact you're only renting, or not participating in the gaming culture.
Probably the 2 most common people that got screwed by this are people that use IFTTT and people that control their thermostat with an Alexa. Google is walking back some of their earlier statements and saying they may allow certain "trusted" partners to keep using the old API, so Alexa users may end up being OK. Another less common use case (but one that affects me) is using their developer API to take a bit more control over things. I use it to log temp/humidity data for my place, and to control my thermostat using Home Assistant.
I actually welcome some of these (one google account, instead of separate nest+google accounts) changes, as it will make things easier to setup for my parents, etc.
