Traditional financial markets already give people really big incentives to cause all kinds of mischief. Eg buy a few puts, then publish some made up bad news about the company and profit.

Somehow that doesn't seem to be too much of a problem in practice.

I don't care if someone tanks MSFT stock artificially or deservedly.

I do care if someone pays the president of Cuba $300k to launch a rocket at a skyscraper in Miami to start a war so they can make $1M.

If you're invested in MSFT, you signed up to be some part of a casino.

If you just live in the real world, you ideally did not sign up for infinite corruption that actually impacts your life just because someone wants to bribe politicians to get an ROI.
