Ultimately, this whole situation is currently a grey area that is being left up to the discretion of the representing GM that gets assigned to the situation until such time the people on the FFXIV team responsible for sorting out the ToS/EULA addendums/alterations can hammer out all the pertinent odds and ends. While they should have expected situations like land-barons and whatnot when housing was first introduced, there is nothing we can do about it now other than abide by the rulings made during the interim. Eventually, the agreements we consent to for this game are going to be updated to appropriately to reflect that a) offering to relinquish a housing plot for anything beyond free and/or b) selling a Free Company with an attached housing unit is against the ToS.

People have to deal with any infraction they receive at this point in time for violating the rules as they currently stand, and understand that FFXIV is not a democracy where the masses decide what is and is not right.
