In case anyone wondered from my previous reply to Searing, that post was not an endorsement of Bitcoin. Why bitcoin is garbage and only physical, commodity currency (aka things like silver and gold) are permissionless and money:
Try to cross any border with a significant amount of PM and find yourself explaining to the tax slave plantation guards that it's supposed to be
permissionless money.
Or just try to conduct any transaction with them. I keep accumulating some PM, but it's just for a sound sleep.
I prefer useful physical items for a sound sleep, like boats. If we have local riots I can bug out, if the grid goes out I have local power and the state is not going to take it away because what are they going to do with it.
