Of course it’s an argument because we can simply license based on predictors of burden. Small dogs which are projected to fall below a risk tolerance threshold should have less licensing burden. Similarly, different classes of vehicles get different licensing requirements; saying all cars are the same is just lazy, and a regulation meant for big risky entities being applied to small ones is what we call regulation moats. We have enough pet owners that we should be able to quantify risks and burdens for the purpose of licensing. Here we have an article which provides empiricism on the community burden from cats.
