Can you eject someone from a building against their will?
Generally no. Throwing someone out typically calls for throwing, and violence is no longer permitted on Disboard. However, moving someone against their will – assuming care is taken to avoid even unintentional harm in the process – isn't definitionally an illegal move. Tet did not excise involuntary experiences from the world, which means that a certain amount of what might be sweepingly termed 'violence' is actually still allowed: playful roughhousing between friends, parents toting around crying infants, compulsory bathing episodes, and other things of that nature. The Elder God of Games remade the world in accord with his own design, but that design had some nuance to it.
Disboard is inhabited by no small number of extraordinarily powerful beings, and were they only prohibited from violence in this manner they would be effectively prohibited from doing very little. The primary check against aggression in the Covenant is the rule against war. Most forms of coercion, detention, hostile magic, and assorted rules-lawyering are in Tet's eyes acts of war, which is part of the reason why Disboard is not a singleton dominated by whoever got their expansionist hierarchical mind control apparatus off the ground first in the wake of the Last War. At any rate, the playful roughhousing stops the moment it is no longer playful.
