You know, every time I see something like this, I really hope the legislation passes. Then as the enforcement attempts to handle their impossible task we get to sit back and watch as Tor and I2P and EFF get funded, citizens and politicians gain a basic understanding of encryption, and governments learn that one does not simply ban crypto.
It would be fun. So more power to them! Let's see Britain create their own crypto free internet! Let's watch the public uproar as Google and WhatsApp becomes unavailable in Australia! These things are just big opportunities to get people familiar with what's at stake.
