Well, in effect, haven't we already approved of this approach, and isn't that what is at the heart of Citizens (hah) Untied. Benjamin Franklin and Thomas Paine had printing presses. To influence public opinion, and get votes, the printed "broad sheets," one large piece of paper, on which entire essays were printed, and nailed them up in public places. Paine never really had money, and Franklin was self-made by virtue of relatively non-political "books."
While at some point, the internet and social media may act as an intellectual conduint. But at the present time, a group of wealthy individuals who choose to create a corporate entity with millions of dollars, and publish anything they want to about a public figure, unless the public figure can somehow meet the unmeetable legal standard of proving actual malice as well as a false statement.
