Yikes!
If I was presented with something like one of these documents at the start of a game where I was playing with people I didn't already know, my eyebrows would go up. I mean, sure, respect etc. is fine, but if the attitude is such that it needs to be spelled out in that much detail I'd wonder about the DM and his-her gaming background. (also, as soon as I see anything about enforced party co-operation and being told what I can play in terms of characters I'm halfway out the door, but then I'm a let-'em-fight DM as well...)
If I was presented with something like this where the players and DM were already friends of mine the debate/argument would start immediately, probably over a beer or two.
I've never spelled any of this out to this kind of degree in my games, and hope I never have to; other than saying that quorum for a session is half the players and if you're not there those players who do turn up will play your character for you. (this usually works out just fine)
As for drinking at the game, I'm all for it.
But then, we're all friends outside the game anyway, so there's little difference between sitting around in the pub drinking beer and telling tales and sitting around at home drinking beer and playing D+D.
