the problem with that line of thinking is that there are plenty of laws that no one follows and are not enforced. They aren't really laws at that point, even if they're still on the books. My favorite is the requirement to stop at the city limits in Ft Worth Texas and sound your horn before proceeding into the city. To warn the horses. Those laws are everywhere and people are in unknowing violation constantly. They may have made sense at some point, or might have even been a joke from the start - it's illegal to each chicken with a fork in a neighboring city here.

We may not approve of it but the reality is, this is one way that our laws evolve. If they become pointless, and most people ignore them, then the law withers from lack of enforcement. Sometimes repealed but more often not; it's just not a real law any more. This particular situation, where there is no possible downside other than someone seeing you "break the law" and thus is consistently ignored, could be seen as belonging to that genre.
