So your ability to spend physical dollars is dependent on if you can physically get to the place you're spending them. Also as I said, no matter the dollar if YOU are spending them, it is tainted by the gayfeds. Just for reference, that is not how most people spend dollars and is literally impossible in a lot of places. Apply this to Bitcoin just a chain of signatures. Nothing about the signature has any identification whatsoever. I can spend bitcoin from anywhere, with no restriction. The fungibility of bitcoin (or literally anything else) is an out of band designation that uses pointers to facts about the item: Serial numbers, outputs, even entire types of money. Fungibility is not a property of money as some people love to say. It is a social enforcement mechanism that is revoked at the moment you are a pariah.
