My son leaves home and buys a house. He wants to be able to defend his family and carry a handgun because the home is in a not-so-great neighborhood. Explain to me how he will buy a handgun and who would sell it to him. He effectively is banned from getting a handgun even if they are "legal".
What you are proposing is no different than a ban on handguns.
i can 'give" a handgun to anyone i choose, including my relatives,
under my new proposal
sure, there are ways around it, but that's true of many things -
if you want something bad enough
