Personally I don't really think it's fair to reclaim housing plots, people paid large sums of gil for those and they should get to keep them. What you should really be asking for is more housing plots. Essentially it would be hurting players in order to give SE a free pass on their bad implementation of housing.

SE actually had plans to start reclaiming housing plots already but those were met with a lot of controversy because they stated from the get go that if they were going to reclaim plots the buyers would not get their gil back. As far as I can tell the idea was never put into place. To me that was a good move on their part because let's face it, things can occur that can leave you unable to play the game due to the subscription costs. Unexpected vet bill for example or various other possibilities. When fufu needs surgery and you have to take a break for a while because you simply can't afford to play, I don't think you should be punished for it.

SE has handled housing very poorly, Yoshi himself said that personal housing and FC housing would be separate and they are not. Additionally there are only enough plots for a very small percentage of the more populated servers. I believe they have good intentions and plan to eventually have enough plots to go around but it turned out to be a bigger hurdle than they anticipated. Once there are a decent amount of plots there won't be any more reason to ask for a reclaim.
