Unfortunately that's not true. "Do business in the UK" means that a single British user has an account on my server. All the western nations have mutual agreements to enforce their civil laws in each others jurisdictions. Look at Kim Dotcom. I feel the same way as you: make them all build their own firewall. But unfortunately these governments don't see it that way anymore.
