If someone spends significant effort to gather documents proving that their family was forcibly relocated from Poland, they may be able to become a Polish resident and then spend a year or so doing paperwork, bringing all of the documents that are required according to the official web site for some task to the appropriate government office where they are then told that other documents are required, or that nobody in that office even knows what documents are required, and so on, and after that time they may achieve Polish citizenship. You know, in recognition of the fact that their family is in fact Polish. But during that year or so, they may have trouble using the banking system because of sanctions on Russia and because no Polish bank will serve them until they become Polish. So their employer may be on the lookout for alternative payment rails.

The person you are responding to is not arguing there is not a use case for crypto in cases like this.

They are arguing that stablecoins, specifically, require an off-chain entity that ultimately control them. And if you have an entity actually in control, why go through the trouble of blockchain? Then you can just have the controlling entity run a normal non-blockchain ledger.

I like the argument elsewhere in this thread that the actual reason is that it allows running a bank while pretending it’s not, bypassing regulation meant to protect depositors.
