Most of the problems solved are not at their first iteration of solution. There will be a next one for most of them as well. None can deny that the crypto field opens opportunities for the next iteration of solutions
Even if they might do things better (which I don't see that happening; solutions are objectively slower and more cumbersome than centralized databases with audit logging), they appear to solve "problems" that aren't really problems.
There's a lot of things that classify as annoyances and inconveniences in the world. That doesn't mean that I'm willing to dump a boatload of cash to solve them.
Identity isn't currently a technological issue. Microtransactions aren't a technological issue solved by blockchains. Ledgers of most things in general don't have a trust issue that's solved by blockchains.
Technies being techies think that technology solves a lot of issues just by existing while completely discounting the issues of trust and control in institutions themselves.
Most blockchain problems are actually governance issues.
The early internet immediately allowed people to do cool stuff that was explainable if someone had a moderately open mind. If wasn’t vaporware.
"Just imagine all those possibilities."
"It may not be there yet, but the smartest minds are working together on it."
"How can you not see what the importance of this new infrastructure?"
"DAOs, NFTs, [insert new useless crypto tech of the day]"
If, just once, they could just provide a single real use case that would actually improve my life... I get it, crypto is great for buying drugs on the internet, money laundering, riding the hype train, speculative investment, and so on. But I just have never seen any real legitimate use case that would benefit from crypto.
