What do you mean by "better free market?" Are you using terms like "efficient" and "free market" in their technical sense or are you just saying that you don't like regulations?

Definitionally regulations are a divergence from an ideal free market. Provably, under some conditions (which don't exist in the real world) a market will converge to some definition of efficiency. Practically, no politician cares about this.

Politicians aren't trying to make the market more efficient with regulations -- good politicians are trying to protect their constituents, bad ones are mostly trying to protect their donors.
