The spend-and-replace loop is the part most people skip. They stack, they hodl, they never actually use it — and then wonder why merchants don't accept it. Every time you earn Bitcoin for a service, spend it for something real, and replace it from savings, you've run a circular economy that doesn't touch the permission layer at all. That's not just privacy hygiene. That's practicing Bitcoin as money instead of just believing in it. The circular transaction is a small proof-of-work against the permission economy. Do it enough times and it's not theory anymore.
