@boxian I'm fine with assuming an idea situation... generally speaking, that's pretty much all rules are - an assumed ideal, and usually an associated punishment when someone deviates too far or extremely from the ideal... (Does everyone go 35 in the 35 zone... But if you go 70 a visit to county court is quite likely in your future.)
I agree that enforceability is a concern, but since a perfectly enforceable rule has never been created in the history of humanity, it seems like that shouldn't be a deal breaker. It seems like delaying streaming by a few minutes is a good practice for players. It seems like a mild punishment just put on the books, one enough to create a social stigma, might not be a terrible idea either.
Rules are creatures born of theory, but they're decided ultimately in the practical realm. Everything has a fail rate, including enforcement for everything. I don't think that imperfect enforcement is that great a reason for not outlawing something. So long as it passes a cost benefit test... seems good to me. Ultimately rules are a collective voice saying, "Hey, don't do that." I'd be fine with being a part of that chorus... even if some people are going to ignore me anyway. At least they'd reduced to being "that guy who won't quite doing that thing." Which would probably reduce the practice a lot.
