As CCP does more and more of this, rich Chinese will start feeling agitated about their government. If they only revolt and elect their own government where actions of thuggery are not ok, they will finally be free.
I know a lot of chinese don't care about the government but such actions of stealing wealth is literally how a lot of revolutionary democracies were formed.
Decades. Also passports. Wealthy Chinese are known to buy significant investor (which is not that significant) citizenship in several countries, not to move there but have an exit option.
Also to be fair I think a fair portion of this is not fear of China changing the rules, often if the wealth was gained corruptly this is a way to protect it and move away from repercussion.
