That goes way beyond the scope of legislation in question. Suggesting that something akin to the great firewall of china could be deployed in the EU is unrealistic - having said that, it sure feels surreal when expression and support of these authoritarian ideas by EU representatives doesn't lead to immediate political suicide.

Why do you think a Great European Firewall is unrealistic?

It would likely break dozens of individual member state laws protecting freedom of speech, privacy, net neutrality, and the scope of policing powers which would have to be changed or grossly violated. This seems, to me, culturally and politically untenable on a national level because the population at large hasn't been condition to accept iron fist authoritarian rule and gross violations of their personal liberties.

First, I was being sarcastic. But in terms of "political suicide", remember that politicians a) have info we don't, b) have fear mongering elements screaming in their ears, and c) have surveillance lobbyists taking them out to dinner.
