Mark,
I think you could also find a quote from one of those Old Scots to the effect of, trees have no place on a golf course. That said, Mac, Ross and others eventually decided that in the natural treed landscapes across much of America, they probably could be incorporated.
Tom said what I was trying to say more eloquently, and I think Mac also said that it is a fallacy that hazards are there to punish, but rather, they are typically placed to encourage (perhaps certain types of) good play. I tended to place trees at the apex of their flight and height, i.e., about 180-200 yards (70% of total distance represents the typical apex and curve bend) to make it easy to curve around to "position A" thus encouraging that shot, while leaving enough fw on the other side to find.
A tree about 80 yards off the tee as described in the OP are more penal than strategic.
Cheers.
