Capitalism is based on the principle that everything has to be privately owned; it can't be held in common. There is even a dogma, which is today called, the "tragedy of the commons" which holds that if things are held in common they are going to be destroyed. If they're privatized, like you give them to Bechtel or Monsanto or ExxonMobil, then they'll be preserved because that's the capitalist's religion.
