Your options for getting rid of it are Congressional ratification with an overwhelming majority (LOL), a Constitutional convention (a horror too frightening to contemplate, given the people who would be involved), or guns. Which do you prefer?
I'm not suggesting getting rid of it, stop with the hysterics. I'm saying it's not a necessary feature of a democracy, as you suggested in your original post.
It is a highly idiosyncratic design decision in one democracy. It is not at all functionally necessary to America's system, and it's certainly not necessary to any other, as proven by its conspicuous absence from said democratic systems.
Five stupid people outvoting four dumb people is a natural outcome in every democratic system. One person outvoting two based on geographic location is not a natural outcome in every democratic system.
It's not that hard to understand if you take off your ideology blinkers for a moment and read the words in front of you.
