1)Why did he build a satellite? Oh, that's right, to monitor the people who wiped his mind, so it could never happen again. He didn't infringe on them first...he retaliated...huge difference.
2)Why did he follow Superman back to Metropolis? Oh that's right, to monitor the man who just FOUND OUT HIS IDENTITY. Hmm, why would he ever need to know the person who knows his identity? Oh I dunno....something about self defense. Huge difference. Clark just x-rayed his mask, without even asking. Bruce retaliated because it could be dangerous for Clark to know who Bruce is, out of costume, but not the other way around (relative to the time that the event happened obviously).
3)Is Batman friends with the crime lords who pedlle drugs and prostitution? Who rape and murder? No..he isn't. Spying on CRIMINALS is an entirely different idea than having your FRIENDS spy on you. Especially when they turn on you. You are making the worst comparisons imaginable. Criminal activity, compared to friends betraying you. And for that matter, the police monitor people at a distance, without your information. In fact, the only illegal monitoring comes to phone tapping, and obviously that changed recently. Otherwise thermal and audio equipment, have never been specifically off limits. How else do you think police organize a sting?
I think all that can be said, can be said. You aren't even making new points, and your juxtapositions are highly absurd. Oh yeah one more thing

I believe he exercised the best points.
