It's not at all clear to me that Mobile IP would be viable at the scale of a modern wireless service provider. It amounts to routing all traffic to/from the mobile device through a machine on the network of its "home" IP address. Without some fairly invasive routing shenanigans, this would be disastrously bad for users traveling far from their home network (e.g. a user gone on vacation).
Not that it matters, really. As far as I'm aware, there were never any substantial deployments of this protocol.
Whether it's workable or not it's besides the point when certainly the UK gov gets it in mind to implement.
Yeah but the digital ID could be the 64bit suffix of the IP. Kind of like that horrendous and moronic idea of using the MAC address as the suffix.

I was more responding to OP's tongue in cheek comment about government assigned addresses
