I agree, but on the other hand:
If you pitch your setting and none of the players want to use the options contained in the pitched setting, you didn't pitch it well. If you got players to really buy in to what you're trying to do and what's cool about the setting, then they should want to work within/alongside it.
In other words, if 1/5 players isn't going along with the idea, it's that player. If 4/5 don't want to go along with the idea, it's either you or the idea itself.
It pretty much goes without saying that if no players like your pitched setting, you better change your pitch/pitch something else!
I've put a lot of effort into finding a campaign that'll suit several players with highly varied tastes (eg my 13 year old son Bill & my friend Kimberly like different things, but they both like dragons, so I chose Odyssey of the Dragonlords for a future campaign), if I want them all in the one game. OTOH I also run games to suit me, finding the players that fit.
