Agree. And it will require a system where it will keep track of sats to dollar/other currency and able to dynamically price the product based on that.

But trying to steel man it.

If pricing on local currency is possible then I guess I'll just start selling phone refills / e-wallet for Indonesia region. I can just do that using my mobile banking app, and I don't mind doing it for 0% margin since I can just treat it as a way to get KYC free sats. Though I believe there will be no buyer since others also have the same access to the mobile banking app
