The rule that you have to log in to keep your house was never implemented, just discussed. It is not in place (unless I'm mistaken, but I don't think I am).
The issue here is not with the FC. The FC did nothing wrong - they bought a plot, and maybe one of them will come back to the game in the future and finally use it. There's nothing wrong with this. What's wrong is that there is a finite amount of land. That's the issue here. If everyone had the ability to buy land, which they should be able to, no one would care if a plot sat bought and unused. Having finite housing, but with no housing market and no management or upkeep means the available housing spots will slowly dwindle while still taking up SE's server resources. This system is bad. It favors no one. SE is spending money maintaining servers for content that is unused by people who no longer play, and as a result, has less to spend on content for newer players.
I really wish neighborhoods weren't a thing. I wish we had instanced housing. For the same amount of server resources, SE could support significantly more houses because the ones that aren't being used wouldn't need to be instantiated. A plot that's never used and has no house? That wouldn't take up any resources at all! I don't understand how the advantage of being able to wander people's houses in an open-world setting is better than the ability to give everyone with means a house. I'm not saying give one to everyone, I'm saying, give everyone the ability to acquire one. Heck, if they still wanted neighborhoods, they could make them dynamic. Every maintenance, auto-shift the wards to include only active houses. Dynamically allocate neighborhoods. Limit the ability for someone to purchase specific housing plots based on what's active so you don't get everyone in the same spot in the neighborhood. But even then, who cares about neighborhoods? Far more people want the ability to have houses, period, but are not able to than who want neighborhoods.
Housing that is permanent once purchased, but finite in supply? How is this still a thing?
