At this point, selecting random people off the street would result in a healthier democracy. Politicians have room to be dumb and evil, because they inherited money and social connections. A rando would have to be actually skilled if they want to obtain such things.

Can you explain in a little more detail how enforcing online ID prevents WW3? Genuinely curious. The only thing I think of that national online ID might help with is counter intelligence, especially in defense against psyops. However, in the few cases that we do know about psyops toppling elections, e.g., Brexit, these were performed on behalf of or with the aid of party and government officials in the affected countries. If any, this would become easier, because widespread online ID silents dissenting voices, while well-financed entities can navigate and / or circumvent such regulation (also see, for example, the effect of GDPR on the market structure of attention merchants in Europe).
