In detail, what is your idea of the perfect government?

Most will probably say ‘no government,’ but since even a world at peace would have to have some sort of government, what is it’s ideal form? In order to make everything work, please provide details.
Most people complain so often, I find myself complaining sometimes but when I think about it, I’m not sure how much better I could run a country. How would you deal with health care, taxes, law, criminals, housing, etc etc etc?
I’m not sure where to go with this…It’s a huge concept for me.
