Um. I'm not SURE but it seems likely that someone's coins could wind up in another person's account due to say theft or fraud (I've seen a ton of frauds in online games etc like a simple raffle ticket game or other things like that). It's not like every vendor, bingo caller, or even poor grandmother asking for extra food money in the world has a little sign over their had saying "She's lying" every time someone makes a transaction (or just before).
So like any time a "police force" seizes goods, they may or may not legitimately still "belong" to someone. Maybe that's why there used to be court systems or something like that. A chance to prove something is yours and to show that you are not, yet, proven to be a criminal when you can show cryptologically that your name is attached to something.
Maybe there's some alternate viable opinion here.
