This is not a moral judgment (I'm too old to make moral judgments). Fact is that purely competitive markets suck because there is no money in them (there's no high growth startups in the dairy industry, even with extensive government subsidies to offset the effects of vicious competition). A good fraction of the opportunities to make money are based on things like arbitraging regulations or exploiting market failures. Much of the rest involves focusing on markets with little competition (either because it's new or because others don't have the skills to target them), but I think people underestimate how much activity is in the former bucket. E.g. with AirBnB: are they in business because nobody thought to do what they're doing before, or because people thought about it before but realized it was illegal?
But maybe that is the exception that proves the rule. Or maybe you didn't mean dairy products.
Anyway, I'm not sure 5 of them would really weaken the point you were making.
Elon states that many forbes list billionaires receive huge amounts of profit from the subsidies (oil, agriculture)
Let's say all of the restaurants in your neighborhood have to charge extra because of the cost of commercial garbage service. And you start selling food cheaper, because you're putting your garbage into the household trash and passing on the savings. Yes, that's a business, but it's basically just breaking the rules and passing some of the savings on to customers.
If you have a two family house and "air out" the second apartment, how exactly is that converting externalities into profit?
I'm not sure a densely populated city should really make any objections to externalities.
Not that all these laws make sense for airbnb, but by not respecting them you're "unfairly" undercutting hotels.
I don't. I think that hotels are just pissed because airbnb provides a fairly thin layer of technology that allows property owners and renters to use their property more efficiently (by having it occupied more often) and therefore threatens the very core of their business.
It's the same story with taxi drivers opposing ridesharing services. Does anyone really think that taxi drivers are mad because they're worried that these new services will provide a less safe or comfortable experience to passengers, which is supposedly the point of taxi regulations? Nope. I think they're mad because ridesharing services allow more efficient use of automobiles and therefore threaten the very core of the taxi industry. Any bets on what taxi drivers will think about Google's automated cars when they start offering shuttles for hire?
If we want to talk about externalities, we should at least recognize the possibility (and, I dare say, the near certainty) that many government regulations themselves have considerable negative externalities.
