> I mean, lots of people/companies hold USD, EUR, CHF, JPY, etc., without ever needing to pay taxes in those currencies.
I don't think vkou was claiming that you yourself need to pay taxes in the currency yourself. Just that the fact that there's workers out there in another country who needs to pay their taxes in their local currency and will therefore need to charge for their work in that currency or trade for it. Either option will lead to some predictable demand that you can depend on whether you pay taxes in the country in question or not.
