I fail to see how class balance issues due to dev oversight and lack of testing can apply to housing. I still stand by and developers do as well, buff a class/feature up to the target level. This makes players happy because the thing they want got better, players on the once OP class are unaffected. Nerf a class that is out performing, people who play that class are upset.
Back on point, wiping out these alt owned houses doesn't solve the problem. It's hardly a drop in the bucket, the only reason it is being floated is because people think if a few hundred more houses open up on their server surely they will get one this time! Surely out of the 10k people and hundreds of FCs on their world without a house. Even if you assume 90% of the houses in the game are owned by 10% of the active accounts that is only 135 thousand houses freed up to be fought over by 635 thousand players AND their FCs. We need to focus on a long term solution, not a short term stop gap.
People are just so upset right now that they did not get a home that right now people are willing to punish other players who may have done nothing against the game rules. House flipping is against the games rules, and should be punished. I do not disagree with that. But to punish every player who has houses on an alt because some players who have houses on alts might be trying to sell it for a profit does not seem like a good idea to me. And the worst part about this is we do not have solid numbers on how many homes are owned by single accounts. Even if we just had a percent from SE 20%, 60%, 80% of total housing is owned by a single account with multiple house owning alts. Currently it is all just speculation and anecdotal evidence just like your insistence that the number of players that are actually going to quit because they did not get a house last night will out number those who would leave because they had their house and items taken from them. How many Paladins ACTUALLY quit when they said they were going to during HW when raids preferred WAR/DRK? What amount the Monks, or the Summoners who were going to quit because Egi's were small?
This Mateus thing, they did nothing wrong per the game. They didn't buy them all to flip them. To my knowledge most of the homes they owned had been vacant for quite sometime and they are not trying to flip them for money. They crafted and decorated most if not all of them. So instead of tearing away all the work they put into earning the gil to purchase those homes(I am sure they were investigated for RMT when that story dropped), the crafting and gathering to decorate those homes, and the time spent leveling the alts for each of those homes for a couple of people who would probably be more than happy to have used instanced housing if it were available.
Instead of striping people of things they worked for, how about we get a solution in place first? What is wrong with getting instanced housing and then applying the 1 per server rule? Because then legitimate players who own multiple houses can have their extra homes transfer to an instance, freeing up wards and they don't have to lose as much? I feel like more of these suggestions are about punish those who have than actually finding a solution.
