This is addressed at a few different points in the article, I found this bit particularly insightful:
> So what happens in practice is politicians write a vague law. Bureaucrats turn that law into very detailed (but often still vague) specific rules. Those rules might or might not be “legal”, but nobody want to risk fighting them in court. If the regulations are particularly ridiculous or likely to be overturned if challenged, prosecutors may quietly stop bringing cases. But the regulations still sit there on the books. And people still usually pay attention to them, because why risk it?
