The value proposition is very straightforward - for the customer to own something unique and expensive. Most wealthy folk assume that if you pay more you get a better product, particularly when it comes to technilogical based products.
For the manufacturer it is a very simple calculation - can you make more by selling fewer, more exclusive, items at a higher price.
This is the inverse of the Levi Jeans saga when they almost went bust lauching a high end clothing. Their value proposition was cheap, rugged clothing, not consonant with high end suits.
The barrier to making these expensive products more affordable exists in the body of this forum - the forum is full of folk who want to believe their clapped out 70’s audio product ( think direct drive TT here ) that cost a nickel in a garage sale is the greatest audio product ever made and can compete with anything made today, particularly when they have added their own unique take on snake oil. You know them, "when I stuck some Wrigleys pepperment chewing gum on the headshell, my 1983 Grace 707 with the wonky bearings blew away an SAT tonearm".
In a shrinking upper end 2 channel audio market the skinflints are killing off whats left of any potential market for innovative product at a "reasonable price".
