Cyberspace is not private proterty the same as land, the house built upon it, or the cars that drive over it. Even if it was, historically, property interests invite governmental intrusion. As examples: zoning ordinances, health codes, building permits, vehicle inspections, and on and on. Public policy trumps private property interests everytime. Again, nobody forced you to buy that house, and by paying the mortgage you aren't absolved of the other responsibilities that come with ownership.
