No one can effectively "opt out" unless they move to a private island with their belongings in international waters and defend their own property themselves. All your liabilities, the necessities you buy, your income, your home and place of work, are all still protected by the same laws, defended by the state, and denominated in the legacy system's money. What people call "opting out" is literally just them buying Bitcoin with their surplus. Thats it. But they're still living here in the same system with everyone else and, unavoidably, dependent on the state to enforce their property rights.(𝐓𝐗𝐌𝐂)
