People are, on average, incredibly stupid. Some of those who aren't will inevitably take advantage of this for money and power. When stupid people use http and see a warning, they don't think, "huh, I have no login here, provide no personal information, and the information I am receiving is not in any way critical--if it is spoofed by a bad actor, it doesn't matter" and bypass the warning. Instead, their little primitive brains do the fight-or-flight herd behaviour and click "get me out of here". This puts the CA in the potential position of extorting money from those who must, of necessity, cater to stupid people. It also gives the CA complete control over who gets to publish their information. Forcing the need for a CA is simply totalitarianism. The only way a CA can exist in a world where https is functionally mandatory is if legislation forces the CA to be free as in beer, fully transparent, and prohibited from arbitrary action by an appeal system that is fast, efficient, and also free as in beer. Otherwise, we have lost everything that was good about the Web. End of story.
