The later seasons explained things a bit more if I remember correctly. There was more to it than what was in the first season.

The second season also went completely off the rails with the mind reprogramming noise that can be broadcast over the radio or a phone line. They also glossed over the whole "Your body will have a police record thicker than the backup dancers in a rap video when we put your mind back in it, and also you will be wanted for treason." problem. Luckily they collapsed society before that problem came up.

Spoiler alert The dolls aren't the only ones that have their minds tampered with by the end of the show.
