It's interesting to think about support for laws that disallow actions as driven by the action itself or "something else." The something else is often the alleged failure or difficulty of enforcing other laws.

For example: if all encrypted messaging traffic was about innocuous trivialities, support for banning encryption would be absurd. The support for banning encryption isn't because people think encryption is bad, it's because governments propose that encryption makes it too difficult or expensive to enforce other laws like prohibition of CSAM, money laundering, etc.

Other examples: KYCAML, drug paraphernalia, Terry stops / stop and frisk, etc.
