Add in the function of the senate and the ongoing public perception of it, and as/if the senate is neutered by populist parties (MAGA/DSA) as they intend to also do with the courts, the argument that the states are sovereign (and they are by definition and constitutional agreement) becomes more and more practically useless, unfortunately (in some ways).

I'm not anti-federal government or anything but clearly we can see that there are issues in how the federal government has become so powerful and yet we're beholden to these two big-tent political parties leaving folks across the various states unhappy with decrees from Washington. Don't like Donald Trump's power over you? Maybe the federal government shouldn't have that power then?
