The larger question is is someone's home worth a war?
I mean that question involves a lot of variables.
And I do think that the Marquis were not in the same situation as people today who are displaced by conflicts or territorial changes.
I'm not saying losing your home wouldn't suck for a person in the 24th century Federation. But a lot of the pain and disadvantages faced by modern and historical refugees would just not be present in a post-scarcity society like the Federation. Not only would they get new land, but their houses and such could be easily replaced. They wouldn't have to do with less or exist in disenfranchised situations where they are distrusted and discriminated against by those around them.
Yes, a guy displaced from one of those planets might lose the exact house his parents built and might never be able again to go that specific river where he had his first kiss or stuff like that. But if he choses to relocate into Federation space he can have a new house very similar to the one he lost and he could even easily relocate to a new river, since with the abundance of inhabitable planets land doesn't seem to be a scarce resource anymore either.
That's why I find it difficult to relate the Marquis to any real life situation, since if they only chose differently, they would have had advantages any real life displaced person could only dream of.
