Because he is one of the criminals using fiat.
Care to elaborate on that statement? I don't think he has done anything illegal-- what he understands is how to utilize the grey areas within the field his multi billion dollar fund operates in.
Just because we don't necessarily agree with these tactics doesn't mean he is doing anything illegal. Similarly, the smart money perfectly knows how to not be taxed their bums off like the regular folks and businesses.
In fact, I strongly encourage the attitude of those who don't just bend over to have the governments enter dry. It's their revenue/profit, so also their right to protect it within what's legally allowed.
