The page you've cited here appears to claim the opposite of what you're claiming, itself citing multiple cases in which the Supreme Court found factually untrue statements firmly inside the scope of protected speech. The counterexamples you're providing are motivated untrue assertions in which speech is part of a broader pattern of action (in these cases, to unjustly enrich the speaker; in others, to unjustly damage someone disfavored by the speaker).
Not that I disagree at all with what you're saying about defamation! But the idea that lies are unprotected speech seems like a very dangerous slippery slope. Like, Singapore would claim to support "free speech" with that (gigantic) exception.
