In a flawed world that deals perfectly with its flaws, infinite storage would be a service you can optionally buy from an open market of third parties, alongside optional identity mediation (for those who definitely don't want their identity bound to a device or SIM or some other PID known to the core network). Bonus points if the technological and organizational interface between third party and core network is paid, I believe that this would be one of the least bad ways imaginable of funding the core network.
