Arbitrary restriction and violation of a protected Right was no part of the power given to the Feds.
Get over it. Don't be part of the problem...
No. The Commerce Clause is general and applies to any regulation of any market. In particular, one of the motivations for holding the COnstitutional Convention was to break up and prevent monopolies, such as the shoe monopoly that ticked folks in a bunch of states off back then.
"Arbitrary restriction and violation of a protected Right was no part of the power given to the Feds."
There's nothing arbitrary about having a list of prohibited persons and keeping them from engaging in any market. That includes the firearms and explosives market. The disqualifiers aren't arbitrary either. Felons have lost their right through legislative action and so have mental cases that have been adjudicated a danger to self, or others.
