> it doesn't believe VPNs should be outlawed

That still leaves space for a lot of unpleasant, but plausible, alternatives:

* Banning under-18s from using VPNs; enforced by ordering Visa+Mastercard to deny UK-originating payments to VPN operators that don't verify their users' identity.

* Introducing a "VPN license"; initially only granted to large corporate users. All encrypted VPN traffic will be required to periodically broadcast their VPN license-number in cleartext so that ISP-based traffic monitoring will let it pass, otherwise the connection will be reset.
