You don't need a license to operate a CB radio. There is very little effective regulation. You're not supposed to curse on CB, but I've heard plenty with no repercussions on the offenders. You're not supposed to use a linear amplifier, but I've heard long distance comms on CB in the past.

The government might like to control it, but they don't have control of CBs now.

Everyone should have a CB radio and perhaps a ham radio as well.
