Waiting to hear what "most people outside the US" are supposed to need those stablecoins for.
If you fall into the middle bands of uses, or in the upper class that can just bend or make the rules, then the financial system is well oiled and it looks like the people questioning it are just cranks.
It's true that a lot of those in the outer bands are criminals but others are things like "buying a truck to build an orphanage for starving Iraqi children just outside of terrorist territory" or "wanted an investment visa in some corrupt island paradise and as it turns out no bank will open up account for purposes of 'international wires to the Comoros' "
Come on now, that's absurd. If this is your best use case for stablecoins - groping for concocted scenarios to rationalise their existence - I stand by what I said earlier: they're a solution in search of a problem.
The other example is somewhat concocted but rooted in the time I spent in Iraq and noting almost all transactions are performed outside the banking system, in part because banking is inaccessible and people often don't have access to KYC documents.
It's really not absurd. As soon as you start trying to do anything interesting the KYC/AML burdens get greater until eventually you realize the compliance officers are just trying to get you to go away (or just deny you outright), get interesting enough and then suddenly despite fully complying with the law you find the walls are closed around you. Most people never find out because they never have occasion to try, they do a bunch of boring domestic transactions plus maybe some international trade with a few well known entities, then they just shout people are making up absurdities.
