There have been many periods in US history where sets of laws were purposefully created that criminalized activities that nearly ~100% of the population engage in. The intent of those isn't to stop those activities, and there's no intent of prosecuting everyone. The intent is to be able to prosecute any individual person or someone close to them, at any arbitrary point in time.

Many of today's lawmakers no longer have that intent, but the system as a whole still keeps running in a manner that allows tools of that nature to be used against targeted individuals and populations.

Yup. Today these are traffic laws (even if you're a pedestrian).

Corporate America is very similar in that regard. If the bosses like you, they will turn a blind eye to all sorts of things. But if they have it in for you, they WILL find a way of getting rid of you for cause.
