Sorry rings, but as I said, because something is difficult to enforce is not a good, or even logical reason for allowing it, and your examples with passive effects proves the point. No playing field, whether it is or is not allowed is going to be even, those coming with fewer friends will be at a disadvantage, no matter what the rules are. Few if anyof the rules are truly enforceable without becoming a much stricter gaming group. That doesn't mean we should get rid of them, it does mean we should give due consideration to why we have certain rules and how they can effect the player base emotionally as well as in play.
You didn't answer the questions I put forward, if FFG banned the ability to watch games in between your own rounds, how would that affect you? How would it affect your experience? Would it have any? If it did have some would it be enough to cause you to depart the game? For me it would not affect me in any meaningful way at all, but I don't assume everyone plays the way or for the reasons that I do. If FFG said that everyone had every right to observe any game including hands whenever the person they were observing was not currently their opponent, it would negatively affect my experience, and I suspect it may negatively affect my playing, but that is mostly conjecture. It isn't enough to keep me from playing, but I would certainly not ever attempt to play this game competitively. I would have to relegate it to purely social, even in tournaments, because anything less would piss me off.
