IMHO, taking away someone's plot of land that has no house on it isn't a whole lot better than taking away a plot of land with a house on it, as the plot itself is very expensive.

I would be okay with something like this only if a player that got "evicted" due to inactivity was given some sort of voucher(s) so when/if they returned they could re-obtain what they had lost. Housing is very pricey, and I don't think anyone should lose that much gil just because they hasn't played for awhile.

Otherwise, it is kind of like saying that only people who will never take an extended break from the game should be able to have a house, y'know?
