"Tips the scale" is a weak claim. They are just saying that all else
equal this makes such policies look a little better. Yes of course to
decide on a particular policy you have to consider all effects,
including "disruptions." On net none of these policies may be a good
idea, even when we realized that the social horizon is longer than the
individual horizon.
