“Gun confiscation”? Yes, for those who can’t afford the $50,000 gun tax. It’s perfectly within the power of the feds now.
How about a conservative gun tax? The next conservative majority can enact or deem passed a penalty of $100 per year for anyone legally permitted to own firearms who does not possess a firearm of at least .38 cal, with compatible ammunition in the home. We can call it the Citizen Protection and Affordable Policing Act. Since unarmed citizens are a factor in increasing crime, this tax on a failure to participate in the firearms marketplace simply encourages them not to shift the costs of defending their lives and property onto other taxpayers. Since the fine is not so large as to be coercive, it's constitutional - Roberts, Ginsburg, Breyer, Sotomayor, and Kagan just said so! Ginsburg even wrote that the commerce clause would permit this regardless of the size of the fine if it's in what Congress decides is a good cause. [Note: I find this idea repulsive as serious legislation, but I'd love to see liberal heads explode when it's introduced in Congress.]
