You already live in a world where anyone can send you any ad they want without your consent, paid for by your tax dollars. The postal service had been trafficking ads direct to your door since before Twitter was a thing.
Billionaires and Autocrats by the very nature of having massive amounts of money can use their money and power to amplify their lies no matter how easy or not it is for normal people to also amplify their own lies. Again, Disney was buying swamp land in Florida through shell companies long before the internet decided forcing Elon Musk to buy twitter would be funny. Or see also that insider trading is illegal for you and me, but if you're a congressman, that's just a perk of the job.
As far as "utterances that no court has ever recognized as speech", I'd be interested in what you think qualifies here, because the recent history (where by recent I mean over the course of the 1900's) has been an ever expansive definition of what sort of things constitute speech. Tinker v. Des Moines found wearing a black arm band is speech. Texas v. Johnson found burning a flag was speech. Brandenburg v. Ohio found advocacy of force and law violations was broadly speech, leaving only a small exception against speech that would induce "imminent lawless action". Hustler V. Falwell found parody of public figures even when that parody intends to cause emotional distress of the person being parodied were speech. Snyder v. Phelps found posters saying things like "Thank God for Dead Soldiers" and "God Hates Fags" outside of a funeral were speech. And let's not forget National Socialist Party v. Skokie, finding that a literal Nazi rally was speech.
