Peace trumps some random pieces of land.
And in the 24th century, where your "home" is just doesn't really matter. The UFP is a utopia where all your basic needs are provided for and you can work as whatever you want.
It's not like now where relocation might mean having to find a new job, a new house, etc.
The Maquis "cause" was just silly.
Silly? These people had made lives for themselves there. If you were suddenly told that the home you lived in was going to be taken from you, the home where you are happy and want to spend your life, you don't just say 'well that's just super, where do I sign up?'. Even if your government was going to pay for a new house, give you a job and feed you. You are happy where you are.
The Maquis were right in there cause. The Federation had no right to just give away those colonies without atleast asking what the people who life there think about it. You talk about Utopia (and as Sisko said, only the coreworlds have real Utopia, the colonies still have to struggle to maintain themselves). In a Utopian society, everybody matters. No one is forced into doing anything they don't want. So by forcing to settlers into abandoning their homes, the Federation is basicly showing their true colors.
Perhaps the attitude of doing what you are told works for Starfleet officers, but a civilian will struggle with that sort of forced relocation. Hell, even Starfleet officers saw how wrong it was and decided to join up.
