That power is supposed to be exercised to enact the will of the people, for the good of the people.

Is it? In the US, our constitution is setup to prevent absolute democracy from occurring. The idea of an absolute democracy where the government always acts on the will of the majority as an ideal is hardly a universal value.

How does a government without power work? How do you take power out of the process of governing?

Yes, that is my point. You can't take power out of politics, and you can't take money (which is one form of power) out of politics. Best you can do is manage it.
