Why should all states have an equal say in how the president is elected? Why should the desires of half a million in the lowest state be worth as much as the 40

Why should all states have an equal say in how the president is elected? Why should the desires of half a million in the lowest state be worth as much as the 40 million in the most populous state. In this context either the 40 million have to give the half a million gifts of tax dollars and policy goals that the minority could never dream of achieving in an actual democracy or they have to give them bullets. Which do you think it would be long term? Can you name another functional democracy of any variety who gives arbitrarily constructed territories of wildly disparate population sizes "equal" say in the running of things?
