Which brings up an interesting theoretical we'll have to deal with in the real world eventually (unless everything gets scrapped and we start over from tribes or something), and that is: what do we do about ill-gotten gains as we transition to decentralized, voluntary, peaceful society?
Here on STEEM it's the ninja-mined stake. It remains the ninja-mined (ill-gotten) stake even if JS sells it to somebody else now. How can stolen/fraudulently/violently-gained property be "washed?" If there's a clear victim, then it seems returning it to that victim is the key, but what about unclear situations like "ninja-mining?"
In the physical world some of the examples would be the insane wealth gained from privatized prisons, running for profit, on the backs of slave labor, funded by stolen money, and fed bodies by sickly named "Justice System." What about when the US federal government simply claimed that all un-owned/un-claimed land was now theirs, and began selling the "timber rights" to private corporations?
How much of the "wealth" on the planet was directly (and trackably) gained through criminal means?
