That is not Kerr's argument. A key point (which he has developed to a very detailed degree, as both a law professor and actively defending people, such as Weev) is the access controls in place.

He's not just bloviating; before you disagree with him, reviewing his arguments is worthwhile. (I do disagree with him in part, and agree with his reasoning but don't like the outcomes in part, but in any case, he's a pretty accomplished lawyer, and I'm not any kind of lawyer, so there's that.)
