If you cost billionaires and a majority of governments a lot of money and they found out then they'd want payback. In this sort of scenario you aren't costing a few places money/lives/stress but the majority of the global world. Crime/Government/Business.
It is essentially as you say but at an overly extreme level.
They wouldn't probably wouldn't publicly execute you on the streets but I could see a lot of them wanting extreme retribution behind closed doors. Like said persons children/family members disappearing, etc. All morals would be thrown out the window. You potentially could bring the worst out of humanity.
You'd have to get caught though. They'd be playing the biggest risk/reward game in the world in this sort of scenario.
