The government is ruled by cronyism and even worse cow tow to people’s worse instincts, superstitions, and prejudices.
The function of government is to make sure those other parts happen - that the capitalist doesn't take the money and not provide the goods (the courts, the police) or provide goods in one place at a low price by dumping toxic shit in another hurting people (EPA), tell you lies and get you to invest in their firm (SEC) or a million other examples. The burden in burdensome regulations is in the eye of the beholder.
Also remember that (at least in a democracy) we are the government. If you don't like what they're doing, vote the bums out. It's a little harder to vote out the plutocrats.
If you live in a populous city in a populous state your vote is worth much less than someone who lives in a rural city in a less populous state.
You’re also assuming as a fact that the court system and the police are not corrupt and can be trusted...
