Sharing the costs of computing and connectivity will allow us to compete head-to-head with the corporations that intend to subjugate us.
We, the users, pay all the Costs incurred by every ISP, web-host, co-lo, online storage, etc. *AND* we pay Profit.
So it's not like we can't afford to co-own those physical sources for our own benefit - we already pay for everything anyway.
We, the users, can co-own the physical sources needed to *host* the software for those ?LeavingTheCloud so that we can enjoy the many benefits of consolidation, though this also brings many dangers.
And so we will need a carefully constructed and legally binding document that we can 'apply' to those physical sources in a way analogous to how the GNU GPL uses copyright to enforce copyleft, we will use Property Rights to enforce ?PropertyLeft.
