There’s no such thing as an informed populous. There never has been, and never will be. There was never a “golden age” of democracy, where everyone dutifully read their newspaper every morning that was filled with articles written by unbiased and objective journalists. It’s always been a shit show. Having some reasonable and well understood requirements for who does get to vote within a jurisdiction is a means to ensure that those who do are doing so with care. Perhaps that’s naive. But it’s no more naive than thinking “democracy”, broadly defined, would improve if we had 100% voter participation.
