I won't pretend to be neutral. As long as the US populace rejects binding a proper national ID (a PROPER one, not the beyond fragile, wholly abused Social Security Number) to their internet activity, this policy is simply a landmine waiting to be stepped on, dozens of time over in quick succession. This can and does work in Asia, but because many accounts require your government ID.
To speculate on your UK laws, that ID difference may be another piece of the puzzle that made this easier to draft a law for over there.
