Why?
Lots of things are effective, but life in a free country means that we don’t do some of them.
We could put cameras in every home, make them illegal to disable. Ban encryption. Censor the web. Ban cars that can’t be remotely disabled.
Free societies are free because there is slack in the system. This freedom is how norms evolve. Gay sex could put you in jail when my parents were teenagers. Supporting Nelson Mandela when he was in jail was supporting the leader of a terrorist organization. Heaven forbid smoking a joint. The status quo is not divined.
My point is, that regardless of your issue, authoritarianism is not a good answer. Even if you think it might swing things in your favor today, there are no guarantees that it will tomorrow.
