If you wanted to force a modern society toward communal ownership of all goods and services, this would be the way -- just make it impossible to figure out who the "real" owners are. Then we'd have no choice but to fall back on "From each according to his ability, to each according to his need".
But what if it weren’t Jubilee, but a declaration that CDOs and other derivatives were unlawful gambling contracts which the courts would not soil themselves by enforcing?
I figured we would fall back on "Possession is [99.99 percent] of the law."
