I don’t know about that, I feel like one of the issues when one person-one vote democracies is that it means the greater population demographic (aka the Boomers) hold a relatively higher proportion of the vote and thus can majority rule everyone else.

The mistake you're making here is in the assumption that voters have any meaningful input on policy. Given the overwhelming majority of policy at both the state and federal level is drafted by lobbyists this assumption seems questionable at best.
