The American experiment was all about splitting the governmental power among different entities, keeping the government small and letting the people preserve freedom and power - while still being protected by the government.
The constitution is a tool to prevent the government from overreaching - and it's been successful at that.
Unfortunately, this experiment also grew in the largest and most warmongering government in the world.
To me, the USA are the proof that minarchism doesn't work and that we need to try anarcho-capitalism.
It's a common mistake to conflate the Gettysburg Address ("government of the people, by the people, for the people, shall not perish from the earth") and the Preamble of the US Constitution ("We the people...")
This is the worst idea I've ever heard. [1]
