Tough to enforce is the point. It means that any enforcement will be completely arbitrary, and based on what has always happened in the past- due to ulterior motive on the part of the enforcers.

It will also mean Google, with their unlimited money, close political ties and database on everyone... will be able to start targeting people at will to have Feds kick down their door and haul them off on charges. Same for just about any company, in fact I bet it comes out that Google were the ones who initiated this.

This is the ultimate extortion tool for the politically connected, and a direct assault on the Republic. It is so frustrating that people take this kind of shit without a peep simply because they assume it will never affect "them".
