We should never encourage ignoring certain laws or it undermines the whole system. It’s why I don’t support states legalizing weed under the federal government’s nose/while they turn a blind eye. Sure, we like it for weed, but what happens when a super conservative state does something less popular like, say, functionally bans gay marriage and goes, “well you aren’t enforcing drug laws, why should they get a pass but not us?”
I’m sure there are better examples but hopefully I’m getting my point across. Exceptions = weakening of the established structure. I don’t know about you, but I like that “the law is king” in the US. Mostly because we can change them.
