Govt: hey these are your UTXOS, I need your keys.
Me: I lost my keys.
Govt: Ok, no problem but if those UTXOS ever move I'll hunt you down.
Me: uh oh, I can't spend my coins.
Discussion
Let me correct this for you:
Govt: hey these are your UTXOS, I need your keys.
Me: No, those are not mine. I don’t have any private key that owns those UTXOs.
Govt: Uh.. Well shiet.
They came to you in the first place because they know you own utxos because you moved from a KYC exchange. Why would they knock on your door if they didn't know it in the first place.
They could try to make you say that you own them😅 But yeah, it’s not this black and white. Depends on how you handled your UTXO privacy.
My version:
Govt: hey these are your UTXOS, I need your keys.
Me: who the fuck are you and who gave you any authority to ask me about my own money.
Govt: Ok, no problem but if those UTXOS ever move I'll hunt you down.
Me: let me know when you can stop me spending them. Now I wish you a nice fuck off.
