The problem with your idea is that it’s not just about the amount of money, but the fact that some people will find ways to have more money, more power. As soon as you draw this line, you’ll have an new level of the richest people.

So in order to really make a difference you would need to spread wealth evenly and no one would be able to earn more than that. And the same goes for losing money of course. This way people will not have the incentives anymore, but i think this will eventually move to a new commodity , because it is just in our nature.
