FF14 is very well designed for housing. Look at all the houses in the game. Look at all the instanced dungeons, zones, and content. Look at the housing items that exist and are constantly being added. The dev kit for world design in this game is probably great.
The problem is they do not want to give that kind of power to players. Or even a small place in the world to players. There is no technical limitations. That is a blatant lie. They do not want to spend the time, and it does not fit Yoshi's 'VISION' for how they want housing to be.
The developers are the problem, not he game engine.
