We already pay a monthly subscription without breaks in between, that's enough for rent I would say.

So even if its minor "maintenance" without any serious benefits (aside from the privilege of owning a house), I see no point to it as the rent would be nothing but tedious. Besides, what are they going to charge us for, aether usage? Next time I need to fend off a primal I'll send them the bill then for my transportation costs, and an hourly rate!
