It's what a lot of web3 believers are trying to build, but it's very hard to both profit and give up control, resulting in a lot of people pretending to do web3 but really it's just web2 with some web3 window-dressing. But, people will keep trying, and maybe they will get it right one day. The dollars right now aren't flowing into web3 though so it may be a while.
The problem is that the technology enables illicit activity on a large scale because of its core premises.
The problem is NOT that people write it off because of the risks built-in to the technology, at least for most people. I'm sure scammers and crypto zealots do consider that a problem.
