There is no "we as a society decide". No one in their right mind would argue that the government widely acts in the favor of those who elect it, especially in terms of revenue collecting and spending. The government decides and the government mostly has its own agendas.

Yet now the correct choice is supposed to be made in regard to property ownership social "harm", using taxes as the specific tool to correct it?

If the government, or "we as a society", can't directly justify their goal being enforced via restrictive law then enforcing the goal via taxation isn't democratically justified (ie: an incentive provided for the tax collecting gov).

>no more of these halfbaked tax reform ideas.

Why would US citizens be in favor of tax reform? What a crazy idea that has zero historical precedent.
