If you think you have rights to your "fake house" till the end of time because you used to play the game, you never read the ToS. Nor any ToS in virtually every MMO. Players do not own anything virtual or otherwise. Its all forever the property of SE.
One thing you need to understand is the high demand for that limited resource you falsely claim rights to. In a video game no less, where most games online interactions dont last past a few years. Option A is to withhold that plot for some player that abandoned it - remember, all SE seen is you just stopped playing. Option B is to free up the plot so another paying subscriber can enjoy the same content you were when you played. Though it sucks you were not playing due to those circumstances, the circumstances doesnt change the logic in the slightest.
By the way, "next time?" Jesus, is that your usual friday night out? I would suggest you look both ways before crossing.
