This is exactly what the Second is intended to take care of

Not it isn’t. The idea that the 2a is supposed to prevent government overreach is revisionist history.

The intention of the 2a was to make a standing federal army unnecessary. Madison didn’t want a federal army, but knew the nation would need some form of military, so he wrote militias into the constitution.

(He changed his tune when the War of 1812 showed him how necessary a true military was.)

It’s laughable to think that people in power wanted others to be able to overthrow them with guns. In fact, rebellions were attempted with guns in the years after the revolutionary war. And they were put down. Never did George Washington say, “Ah, these men with guns seem to think we are being tyrannical. We should reconsider.” No, he said, “Pay your fucking taxes.”
