I don't have enough knowledge on issues like this so I'll take a crack at it. The original act states;

To address the problems of interstate trade barriers and the ability to enter into trade agreements, it included the Commerce Clause, which grants Congress the power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes." Moving the power to regulate interstate commerce to Congress would enable the creation of a free trade zone among the several states; removing the power to regulate international trade from the states would enable the president to negotiate, and Congress to approve, treaties to open foreign markets to American-made goods. The international commerce power also gave Congress the power to abolish the slave trade with other nations, which it did effective on January 1, 1808, the very earliest date allowed by the Constitution.

Seems to me it all started to address problems with railroads moving goods through state lines. Now by 2024 it has been updated to include all sorts of stuff including gun sales apparently. Like every law enacted, it starts to take on a life of it's own where the government eventually claims a right to everything.

I was arguing with some lefty at work one time where he was telling me that the word regulation in the original wording of the 2nd amendment gave the gov cart blanche to regulate the fuck out of it. Text here;

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

I think the issues with guns has been so bastardized over the years that the gov can claim any right to anything where they will eventually convince the people that no where in the wording do you get to own a gun, only we do. have a nice day.
