They can, but both of those are often encrypted such that it is at least hard. TPMS isn't encrypted so it is easy to figure out what cars are going by.

You can get close enough just clipping some weights of the same weight as the sensor to the valve stem. A static balance isn't hard to do - not nearly as good as the proper dynamic balance the tire shop will do, but often good enough.
If you didn't check your tire pressure in the last 20 minutes how do you know you didn't just drive over a nail and get a slow leak? TPMS checks every few seconds so you know when there is a small problem. Anyone will notice a fully flat tire, but a lot of people used to drive on low tire pressure for months without knowing. Once someone knew their tire had a problem they would check daily (until they got it fixed), but many people never knew in the first place, and even though who did know often took a week before they found out - they of course have no way to know since nobody checked their tire pressure daily much less every 20 minutes.
Depends on the attacker. The GPS is better if you have access to the car, but getting that is hard. Any idiot with a radio can read the TPMS sensors of every car going by - there is nothing that even slows them down.
I don't care why. That is still libel and it is illegal for good reason. if you can't stop this for all cases then you ai is and should be illegal.
What matters is the whole community. Statistically it happens to someone in your community. Society wasted a lot of fuel (read global warming) just on low tire pressure.
Surveillance is a problem. So is global warming.
