But wouldn't this affect very negatively the whole community, not only normies? The only "safe" way to "have" #btc would be via an #etf, since your name\ip\whatever is never linked to a specific #utxo that is going to be used in the future in some illegal stuff, no? I find it scary that the initial idea I put forward could be used by the government so every bitcoiner just gives up in fear of incarceration for a crime someone else commited. I feel this is one of the biggest risks in bitcoin. Don't you? Why?

If you are scared then only sell to an exchange, but self custody in the mean time. The brave individuals will sell their coin p2p, and good for them.
