Like, they still need to eat the costs: transaction fee, percentage to the artist (if that’s configured on the platform), and any costs to convert/move currency. As well: I can buy my $200k house from myself for $5m, but I still need to get the $5m. At that level maybe I can game the system (owning 5 properties on that block and selling when the “neighbourhood is valuable”), but this kind of system gaming is as old as money itself.
