While you're not wrong, there are plenty of inactive voters, I sincerely doubt they'd vote in any way that isn't already highly consistent with how votes are already allotted. Say there are 40% of inactive voters (the number is much higher in the US) and you get them all to vote somehow. I'm willing to bet those votes don't dramatically shift election outcomes in any significant way (beyond ~1%). Sure, that'd help in close races, but not much else.
