Why should people residing in any geographic group intentionally be given outsized political power when picking the president? Giving equal input to every voter is not advantaging non-rural people over rural people, it's advantaging more popular political policies over less popular ones.
While people living in rural areas may have distinct cultural values and may face real inequities when it comes to infrastructure, economic opportunity, education, health care access, etc., this seems completely unrelated to deciding the fairest way to pick a president.
It’s pretty simple that the reason to give disproportionate power to small states was to get them to join the USA.
I’m not sure it’s possible to convince small states to give up power now that they have it. Although I’m sure they may want to cecede. Can you imagine the immense power that Wyoming would have as a sovereign nation? Or Delaware? They would be protected from threat by being surrounded by the US and could become havens for activities not allowed in the US. Basically become super Switzerlands.
