How do you limit pollution or resolve disputed. You know the fire departments used to be independant businesses. They would sell plaques to put on yout building. If your building was on fire and you had the right plaque it worked out if not, sorry. So we do not do that anymore.

Discounts for fire services, if you have a subscription. Full price if you don't. Private arbitration for disputes, including pollution (if you can prove harm).

What about sewage treatment?

Do people value getting rid of waste? There you go. I'll have my truck around to empty your cesspool (or whatever method the market chooses).

We have sewers and a treatment plant wear I live. How would you make that happen in your silly society. We just had a new bridge built and expanded our transit system. How does that happen?

The people who value it will pay for it. If they don't what is the justification for forcing people who do not value it to pay?

The only justification needed is the collective good. That is the future. The selfish actors are destined to lose in the world that is coming. The theory you are pushing is a last grasp idea of a dying system. Your arbitrator will often just side with the person that pays more.

If the collective good were served by torturing one individual continuously for the rest of his life, would that torture be justified?

That is a silly question. There is no circumstance that would fit that criteria

You are also discounting what someone else would see as "good".
