This notion always puzzles me. It's not a complex idea.

Just like, say, banning GMO bananas. But such regulation is a whole text which may need to define or refer to definitions of "GMO" and "banana", specify what's banned, exemptions, enforcement authority, penalties, and so on. Maybe 10 pages of legalese. It requires time, expertise, research. But it's still just a ban on GMO bananas.

Or a programmed UI button to show a message. Simple. The specifics of the execution are a separate matter.

It's not "indescribable", but no one will describe it to you ad hoc and expecting it is silly.
