This was tried with Slavery, it was very popular with the two political parties, and it led to a civil war, whose conclusion was: no, states do not get to decide on slavery, and additionally they do not get to secede if they disagree with the federal government. That being said, I don’t think any of these three particular things would become the underpinning of a society or an economy, to the extent that slavery was in the antebellum South. So, there probably wouldn’t be another Civil War fought over it. I think the 2nd amendment one is the most interesting one to me, since our interpretation of it has become so distorted with the passage of time, and since we don’t seem to be converging over time on a consensus (unlike the other two, which were basically contrived for political purposes in the last generation). It’s almost impossible to imagine what the founding fathers would think about its application today.
