It wouldn't be a very elaborate rationalization. e.g. "Banks have KYC and AML requirements. We have an information economy. 'Misinformation' is the equivalent to funding terrorism. Therefore, information-exchange platforms will also be required to perform KYC and AIL or be prosecuted. Compute providers, ISPs, payment processors, and crypto exchanges [assuming they still exist when this hypothetical is actually proposed] will be forbidden from serving any platforms that don't."
