Everyone seems to forget that using VPNs to violate your local laws gives lots of good ammo to the authoritarians that want to ban VPNs. The answer isn't to use a VPN to get around it (and thus give fodder to your enemies) but to change the law.
But it's easier to ask a relative few ISPs to block VPNs than it is to police the behavior of millions of individuals.
While I agree with this in spirit, here in the UK both major parties along with the public at large generally support these types of laws.
