The cancer is a lot of things. It's not just "relocation".

First, the fact that they grandfathered in player's with multiple houses when they issued new rules. It needs to be 1 house per account.

Second, the click system to get a house needs to go. Players are to blame, because they abused the system. But SE needs to come up with something better.

Third, SE needs to add more. 30 more Plots per Ward would give us 10k per world with Ishgard, which is a good start.

Fourth, the size of things. FC rooms and Apartments could be made the size of Cottages. With a basement area.
Add in an instanced garden for them. Or better, an indoor item that can grow 6 plants in a 2x3 square, like you can put outside.
Add Workshop access to the Lobby of an apartment, as well as an interactive door to non-FC houses that can access a Workshop. Make it less than an FC if you want. 1 ship, 1 sub, etc.

Do that and things wouldn't be so bad.
