I'm not sure the political currents present in America today indicate that states won't eagerly trample the right's of their citizens. Especially considering the voting restrictions and minoritarian rule pet projects of the right.

America is also rife with examples of the federal government intervening to protect citizens from their states — Brown v Board, or most extremely the Civil War.

"People need to vote" is insufficient for regressions on issues that affect people's livelihoods. For example, Texas has a larger democrat-voting population than many blue states, "just voting" won't do anything to improve their livelyhood in the foreseeable future.
