I would be happier with something the manufacturer was confident was serviceable. Control boards that approach the cost of a high end smartphone are unreasonable, but also common.
I wonder, truly, if this would be successful. I have no way of even wrapping my head around how to get something like that off the ground.
I think if someone designed and shipped a car, for instance, that was completely serviceable by the owner and designed with that in mind first and for most, you could easily disrupt the car market for a very broad amount of people today.
In the last 15 years, I can only recall one time a car went into a shop for a reason other than the above and that was an independent shop where I was too busy to deal with the job. That's across a Mercedes, a Jeep, a Honda CR-V, and Alfa Romeo, and some classic Mustangs.
There are a few marques that are DIY-unfriendly (hello, BMW), but most cars can be effectively DIY maintained. A DIY-friendly car would not be as disruptive as perhaps you think.
Combine that with trying to keep parts compatible over years and you would develop a following.
I don't want a good warranty, I want a well working equipment.
I think if I have learned anything from Silicon Valley though its this: Never assume that these assumptions are categorically true, or that they were undertaken with due diligence.
Perhaps it is true, and there is not enough interest in this to justify it happening. What if, though, they didn't do the market research properly? Or steadfastly, it actually didn't happen at all?
Your observation is spot-on.

That household refrigerator that was $329 in 1952? $3024 in 2017 dollars.

From that page, it looks like the price of the washer, adjusted for inflation to 2016, is $1756.12. A comparable washer today, from Sears, appears to be somewhere in the $400 - $600 range, or about 30% as much as it used to cost.
Data for today's washers: http://www.sears.com/appliances-washers-top-load-washers/b-1...
According to http://www.thepeoplehistory.com/50selectrical.html a washer and dryer set cost around 500 USD (in 1953 USD) which according to http://www.usinflationcalculator.com would be around 4500 USD in 2017 USD.
Since I'm not from the US I don't know what's popular there, but if I look at http://www.homedepot.com/b/Featured-Products-Popular-Laundry... it seems like they go between 500 and 1000 USD. So between 4.5 to 9 times cheaper than in 1953.
Personally I usually perfer the least features possible mainly because more features = more stuff to break.
