Falling, the auto demolition is necessary with all persistent housing systems in any game. It creates a limited number of houses/wards for the whole population if someones not subscribing or playing, their house should be auto demoed after a fair amount of time to allow someone else to acquire it use it who will hopefully actively use it. If you want to a housing system that dosen't require auto demolition you need instanced housing not persistent housing. Forty five days is plenty of time to allow for someone to keep their housing plot/plots from auto demoing if they care about them. If someones not playing or knows they wont be able to play for more that 45 days they need to prepare for that scenario the world (Servers) keeps spinning in said absence.
