I think it is because we have too many VC-funded startups that are only marked to market every other year, not like a fragile self-funded bootstrapper that has to fight daily

That's an interesting idea! And I probably agree with!

My theory is that the UX sucks because investing was the main use case for a long time.

And when you tell people "Invest in this dog coin and you'll get 10X" they can jump through hoops to get there. But if you tell them "Use this web3 app and find new interesting people to talk with" then their UX tolerance is lower.
