> If alternate techstack/payment systems pops up and reach tipping point, country A can just say to country B who only wants USD (due to alignment or whatever), I don't have enough USD, here's RMB & cips/Brics+ & mbridge basket of equivalent value.

Alternate payment systems aren't even required for this. If other countries are trying to divest US dollars and country B is owed "US dollars" and country A wants to pay in something else, country B would want to accept the something else of equivalent value because it's trying to reduce its US dollar holdings and would just be immediately turning around to resell them anyway.

Conversely, if country B is insisting on US dollars for alignment reasons while other countries don't want them then that's only providing country A with the opportunity to divest its US dollars by using them to pay the debt. Then country B ends up with them, but now what is it supposed to do with them?

The real reason those sorts of debts result in stability is that all the countries owed a lot of US dollars are going to do what they can to prevent the US dollar's value from declining.
