They could take some other cost-cutting steps with a housing system without auto-demolish if the plots were made abundant. Like if someone’s subscription lapsed for some time, then it’s entirely possible to move that data to cheap but slow storage. Then people still have their old stuff as an incentive to get back in.
It’s mainly to do with the neighbourhood concept they use. They keep all the housing loaded up because they’re legitimate zones you can enter, log in or out from, teleport into, etc. Because a lot of those things exist regardless of the housing owner playing or not it’s not really feasible to archive it because other players also see it and access it.
