There are plenty of rights that aren't "practical". The right to vote is a HUGE pain in the ass, you have to organize massive elections. Property rights means you have to have huge police forces. The right to protest comes with enormous practical difficulties. The right to education means that you have to have expensive public school systems. The right to an attorney in a criminal trial means that the court has to provide one, at some expense. All of these are "rights", in all modern free countries, and they are all "magical rights created by law". That's what a right IS.

You're making the wrong argument. You're saying "this is not a right that can logically exist", which is nonsensical. Of course it can. What you should be arguing is "this right is far too burdensome on society and should not have been passed". I personally disagree with that, but it's at least a valid argument.

It takes no effort for you not to violate Title II, just don't ask for other people's personal information.
