1. Players will be able to free up spots for each other through communication and coordination. Is there a potential bias to this? Of course. MMOs are about making friends, so what's stopping you?
2. Buying from someone who supposedly 'gouges prices' actually gives you value for your money, as you are acquiring the plot without the added anxiety of this toxic competition for what should be a feature for everyone.
3. Reporting players has always been a feature, and if someone is going in with this kind of transaction, they can prepare screenshots to make sure the seller remains true to their word, or report if they are charging well more than is necessary (which can always be established as a rule, ToS changes often).
4. Meritocracy has never worked. The random timer has forced people to suffer just for a chance at a home. The moment a game causes you genuine distress just to use a basic feature, you know it needs reworking.
5. A player housing market for all its flaws allowed players to have a degree of control. The beauty of FFXIV is that it doesn't resemble the real world entirely in its economy, as the game doesn't account for inflation in the player economy. Anyone can get the money needed to buy from a seller, and in a much shorter span of time than we'd expect.
