That’s such a slippery slope. For all intents and purposes, that bitcoin could have been lost, stolen, etc. and the govt could not prove that.

No one actually owns bitcoin they temporarily are able to sign for UTXOs.

Just ask the guy who is locked out of his Bitcoin wallet with hundreds of millions of dollars. Is that bitcoin his? No, he can’t sign for it. Will it one day be his, maybe, maybe not.

But, also he is the first major bitcoin billionaire that renounced. That obviously comes with a target.
