I don't think that this is a technology problem - it's a polarization problem. No amount of technology traveling at the speed of light will solve the simple problem that you belong to an ideological sub-group that
ferociously disagrees with another sub-group about how things should be run. Indeed, we're a nation of 330 million people, this is to be expected. I'm amazed we've been able to get away with this level of centralization for this long.
This isn't all that different from the EU, a similar union of states with a similar population (500 million), where the vast majority of laws and regulations are passed at the member-state level and not at the EU level. Any American that argues "each state will handle things on its own" is just making the same argument that a European might make when saying "we should enact this healthcare system X, or that pension system Y, or that policy Z in Germany".
This was always the Framers' intent, Hamilton himself was well aware of the perils of the Tyranny of the Majority[1]. The prescription for this was to apply the subsidiarity principle and use concurrent majorities (i.e. "let the states decide"). Federalism was never about the logistics of walking to state lines.
