You would be breaking numerous laws, your transmitters would be removed quickly, you would be out thousands of dollars in equipment, and no one would be on your network anyway. You would almost certainly go to jail if you tried this.

Have you ever actually read all the laws? It's functionally impossible to survive without breaking laws.

Not that quickly. Tracking down a low-power transmitter in an urban core is technically feasible but a lot of work. Police don't like doing work.
