> the cold north whom has 60% of the population votes to ban air-conditioning, leading the 40% in the hot south to suffer.
This is solved by better legislated states rights not by creating a less undemocratic voting system. There is no reason why the fed should be allowed to ban something like air conditioning or showerheads. But now they did, people in low water states complained that saving water is important since they lack water, so now even in very water rich states it is illegal to sell high throughput showerheads. So the current system doesn't protect against such shenanigans at all.
