All of this was obvious 8 or so years ago during the first real boom when cryptos pants fell down. All hype no usecase. Here we are now how far along in (20 odd years?) with how many smart people making a genuine concerted effort to build something useful (literally millions over the years?) - and still the only useful thing anyone has ever done with blockchain is buy drugs and have a good time.

As I say, crypto is only useful if the whole world is already on the chain. Until then you need to trust outside sources which undermines the entire deal in trustlessness and undermines it in performance.
