What kind of actually effective controls do you think could possibly exist in a world where everyone can buy the data except the police? Aside from the fact other people and corporations can do quite a lot of horrible stuff to you, including turn the government on you - the obvious outcome is the police would simply use proxies and parallel construction, no matter how "illegal" you make it. It's one thing to say they shouldn't be able to do it and we need to pass a law, it's another to create a world where they actually can't, and aren't incentivized to. As a whole separate question, do you think companies and individuals should be banned from voluntarily giving data to the police, out of ideological motives or generosity or whatever? That also just intuitively seems weird. Charging a fee for something you're happy to do is just a small jump. The problem is the mass collection of data in the first place. Once you have that, the rest is inevitable. Mass data collection is a massive qualitative change to what we had before.
