"where a single chip can cost 300$ and has to be shipped from mainland America..." that assumes that the failed part is even available. I'd sure be irritated to have the controller board for a Cadillac XLR convertible top fail and have to shop junk yards, no doubt the wrecking yards are hip to small things of value that they can store on a shelf somewhere. To be fair, I know more than one purchasing guy, usually in boutique electronic product companies, who spend a fair amount of their time tracking down obsoleted parts on eBay to repair or build one last batch of a metal box with circuit boards inside. It's just the nature of modern times I guess, but luckily we can often pick the era we want to live in in our personal lives. I just need to stock up on old Thinkpads, avoid home automation, and carefully choose any car purchases.
