" even in your ideal society you need some intermediary principle or entity to enforce the rules.."

Yes. Voluntaryism and a government who's only job is to protect my property rights. My land, my things, my body.

For it to be a real social contract, it needs to be voluntary. Someone would have to go to my door and present an idea to me, and I would have to purchase that idea, and sign my name.

It is just about things being voluntary or not. Taxes are theft, because I never signed to pay them. If I had the choice I could have signed it..I don't know. Maybe? But most likely I would join another society with no redistribution of money. I would like someone to protect me and my property, so perhaps police and military is ncie to have. Other than that what use is the Government?

I follow and agree to certain rules if they match my principles - because to me there is good and evil. I also follow some other rules, but that's because I have to under the threat of a Gun. I don't believe in God, but I believe in good deeds and bad acts. I'm not a relativist. I follow my own morality and my own values. And there is some objectivity to that. No one has a value or morality that is " I try to kill as many people as possible, and at every chance I have I steal or rape" Those are not great ideals or values. They are objectively evil ideals.

Thanks for the comment man!
