“If Parliament enacts that smoking in the streets of Paris is an offence, then it is an offence”

This is not an enforceable law. It seems predicated on the notion that VPNs can only exist as a commercial product, but all you need is two computers connected to the internet.

Not totally enforceable, but there are not a whole lot of people with connections in other countries willing to host VPNs for them. Most people don't even know what a VPN really is.
