> What is wrong with the current web hosting model?
If there is criticism there it is that people seem to want ever more centralized things, not more decentralized ones. While this may not be the intent, it certainly seems to be the effect.

I don't believe it would be /much/ better because much like early web services/sites/hosting which *were* very much decentralized, they gradually (via the application of significant pressure from large companies) concreted itself into the web we have today. I suspect that no matter how cool of a decentralized application layer you build on top of the internet (nostr, e.g.) it will at a higher and higher level be pushed to centralize further and further either via people's tendencies (as they have learned on the modern web), market pressure from large companies (as we can clearly see), or some unholy combination thereof.
It is a pessimistic view of the future of nostr or whatever replaces it, but I think it is reasonably grounded in history.
It is also why I think some people have such scorn for the vapid enthusiasm many nostr users have about how bitcoin is going to change the world. We've all heard that before and been burned rather badly, if the state of the web and internet is anything to go by. Blind enthusiasm will only make us all worse off. At least the first time it happened people could say "How could we have known?" because at least it hadn't happened before. The potential for nostr to be co-opted into something unimaginably worse is unappetizing at best, and downright revolting at worst.
