allowing those individuals to make What should be collective decisions

What should be collective decisions?

he still pollutes

Not invariably, if you charge him for it and have sufficient enforcement, the pollution will be incidental.

you give property itself rights

Please explain, I don't see how ownership does that.

without violent enforcement?

That'll be inevitable either way, if nothing else to prevent assault.

co-opting the very violent enforcers for their own means ... or purchasing the regulators and regulatory bodies

By making a democracy structure that is minimally influenced by money by highly valuing the opinion of the people and heavily regulating campaign contributions.

inevitable outcome of the system

Please point to those. Seems to me like you get cycles of increasing and decreasing capital control.
