I say, let them try to own the world by conjuring up tokens, meaningless as they might be. It could simplify things for some people - the unbanked come to mind. It could simplify trading - tether, for good or bad, has been facilitating whale trades for years and might be a part in decentralized exchanges over L2 in the future.

BUT when you issue them, whatever your reason may be, be ready to pay back cash or similar "hard" assets whenever someone wants out of your Monopoly money. Or else.
