I approve of regulation if it prevents people from having their coins nicked by the scum/ idiots that infest much of the current BTC space.

If governments attempt to enforce things like seizable addresses then I'll be going black or drifting away. I think many of them are bright enough to realise that working with it helps everyone. If they attempt to impose their will then it's going underground. It'll be a fraction of what it could be, but it'll still be out there somewhere.
