Correct up to a point. The "representative" may not pass a (consittutional) law that subjugates any of the rights of the individual. Government is supposed to be, in actuality, nothing more than the collective power of the people and of the states used to guarantee the life, liberty and pursuit of happiness of the people. It should not be able to dictate matters of personal behavior nor should it be able to intrude into/onto private property. We understood this concept in this Country until roughly 1913 when the federal government began sticking its collective nose into the everyday lives of US Citizens. The federal government that our founders envisioned was to have practically no interference with the daily lives of people and the individual states were not given much more power than the feds. As we have become a nation of whiners, convinced that the "government" can save us from unwanted circumstance, we have forgotten the principles and beliefs that our forebearers fought and died for. Sadly, to our own detriment.
A representative may pass laws on anything not permitted in the Constitution.
The Second Amendment is one expressly permitted activity. But, since the representatives have not stated that the states will follow the Second Amendment, the only amendment by the way, the states continue to pass laws on guns. I add this second paragraph only as further clarification of what I am talking about.
No, no no, they always had absolute power, but just didn't realize it till the last 70 years. Those stupid founding fathers - They could have banned the opium and pot they smoked, and didn't even realize it. The Commerce Claus was intended to give the Feds power over everything. Those idiot dead white males(/sarcasm).
