The renters suffering aren’t actual current renters so much as the would-be renters who can’t actually become renters in the City because there are no units available for them to rent.

AFAICT, no one said it was unjust that nonresidents don’t vote in city elections. It was raised as a reason the policy was unlikely to be changed at the city level, because the people adversely effected aren’t voters in the city.
Those people have no voting rights in the City.
