Ahhh... this is interesting! I agree with you that rules are needed in a community, in a market and within a government. 100%.
I do however believe, that it is 100% possible to create and enforce these rules in a private way, and that this in fact, has happened (and is happening) around is every day.
Therefore I do not think we need the government which in my opinion is morally indefensible. All we need is market dynamics and individuals.
