The intent of a bunch of folks who kept people chained up in barns is irrelevant, the intent of the 1700s circumstances is irrelevant. We're heading to 30% of Americans controlling 68% of Senate in '40, minority rule by rural white folks. This veneration of the parchment as a religious text is just an excuse to not use our brains to solve present-day problems.
(Land ownership shouldn't matter in a democratic republic, people should.)
Land ownership has nothing to do with anything. Everyone gets to vote for their Senators (except people in DC). We did away with the requirement to own land a long time ago.
If California broke up into 200 states, would they need 2 Senators each to protect themselves from being steamrolled? If so, then why don't Californians already need 200 Senators?
