I wouldn't disagree -- but Zero's position is to require that sane law abiding citizens live in a cage, and allow the mentally ill and criminals free rein.
I think that the recordskeeping in Obamacare will flag anyone on mood drugs (Prozac, Paxil, Ambien...) on the NICS system so that these people can’t purchase a firearm.
With better recordkeeping, they can do it by family, dwelling, or neighborhood.
