Because we've done nothing to eliminate the "tragedy of the commons".

Under this scheme, which alternative is easier for users?  I would
guess PI space.  And everyone would choose that and then tell us that
they are sufficiently "special" to get PI space and then we end up
back where we are today.

A workable architecture has to constrain the users into doing The
Right Thing automatically.  Because otherwise, users will optimize for
their own benefit, at the cost of the network.
