Why doesn’t it make sense to use your USD based credit card in France? I use both EUR based credit card and my Bitcoin wallet while travelling in Mexico, Colombia, Brazil, Costa Rica, Panama, and setting up bank accounts in those countries would be infinitely harder.
Regarding hotels and flights, I book it on internet, and I don’t even know which country the travel agencies are located, and I don’t care.

I see your point. To be more precise I use the MasterCard payment network that uses a combination of Mexican Peso, USD, and EUR in the background to settle with the merchant’s bank periodically in the background (and as I use Revolut based Mastercard, it’s even more complex).
Last month the biggest POS company integrated the lightning network, an international payment network protocol, that uses Bitcoin as its settlement currency and Bitcoin network using Strike, and as the POS company does the settlement with the credit card company, the merchant in practice doesn’t see the difference between accepting credit card payment or lightning payment, as it doesn’t handle any of the two (the POS provider handles them).
