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.
I also don't entirely understand why you're even rationalising the purpose of the account to the bank. Can't you just open an account for any purpose? It takes me five minutes to open an account online, and I've never once been asked to explain or justify anything (in many decades). I use my accounts robustly, including for international transfers (I've lived on two continents in the last four years). I even once paid for a trip to North Korea out of an ordinary bank account. My bank never batted an eye.
Maybe you're just dealing with a bad bank, or an over-regulated banking system (Europe?). You realise you can walk into any US bank right now and they'll just open an account for you with nothing more than some accurate ID? And the same holds for much of the rest of the world? The problem you're trying to solve is already solved.

Unsophisticated semi-literate farmers are the last demographic anyone is reasonably expecting to open their crypto brokerage accounts and start trading synthetic USD derivatives.
These are just not realistic scenarios. This is what people say when they rack their brains trying to come up with some reason stablecoins might be useful. I feel like you're just confirming that they're a solution in search of a problem.
There's an ocean in the way, not to mention how risky visiting looks right now. I changed my name recently and the one US bank that I managed to get an account with (so that US clients can pay me without weirdness) won't accept any kind of documentation without going there in person (and I'm not sure I can provide anything they'll accept even if I did go there in person). What now?
People in the middle bands of uses are just ignorantly bliss. And moving between "2 continents" in some vague most likely semi-developed white listed countries in most cases doesn't fall outside the middle bands of uses. So you end up with people shaking their fists at the sky crying that crypto exists, with their fingers in their ears and loudly proclaiming anyone using it are just making up absurd contrived scenarios.
