Personally I find the $1800 sticker shock must be affecting public perception much more than durability issues. Or put another way, I suspect the people that buy this are buying a $1800 phone every year anyways and don't need to worry about durability - if it happened to break mid-year can always buy another one.
That's why I haven't dipped into foldables. Long term ownership seems like such a gamble. The risks are getting lower but still not at a level I think justifies spending that much at once or over a couple years.
