The rights of minorities don't matter?

paying in a currency/asset of your choice is no one's right. I have a bunch of foreign currency in cash lying around which I cannot use where I live without exchanging it, I guess that makes me a minority as well - should I make a fuss about my european country of residence not accepting a central american currency?

Paying with x thing was never a right to begin with
