I’m not sure about patchy. I transferred money about 10 times this year and all the recipients wanted Zelle.

All of your other criticisms are valid, but also exist in a system where you trust your wallet with a third party service. the majority of Americans would use a bank like service that manages their key instead of managing it themselves.

You also ignore the other risks that crypto introduces. Like losing your key, password, your exchange gets seized, your exchange just straight up steals your money, or having a 1 character bug in a smartcontract.

All of those failure cases you mention have mitigations. Dealing with banks? Not so much.

And I'd go so far as to call what the majority of Americans prefer wrt. key management a result of inertia due to a few centuries of having always done it that way. That's not necessarily surprising, a lot of this is new and doesn't have a good "real world" analogue to tie back to.
