If you say so.
We’ve been trying to find a logical reason for these rules for over a day now, and we can’t. Every single justification makes no sense, so we’re left with “it’s the rule.” I mean, you literally just answered my “why ban them” question with “there’s a rule”, so it’s not just me that says so, you do, too.
Shit, anyone can read a rule book. Existence of a rule doesn’t justify the rule.
