The entire economy needs to be restructured, and "value" reevaluated. This idea about tokenized wealth is not the solution, no matter the medium exchanged. Shells, squirrel pelts, gold, coins, digital... It really is all just the same.
At some point, if we don't kill ourselves first, we will grow out of this infancy.
