But I think the way the US is set up (districting, gerrymandering, redlined, electoral college, etc) makes it far too easy for fringe beliefs to take over and dictate policy. So having states simply being more independent puts up far more barriers to all of us just losing our freedom.
I live in IL. (Not near Chicago). My kids public school only gets about 15% of its funding from the federal govt. We could just finally stop having our stupid flat income tax and make up the shortfall. It might set back the universal preschool system, perhaps (which would be a tragedy but better than complete destruction).
Meanwhile, schools might not even exist in many other states if federal funding disappeared.
