You're also not using money to circumvent the normal process we use to proliferate good ideas. If something is good, tell your friends about it. Notably this is exponential and very weak initially, hence the need for legitimate advertising. You may need to circumvent this process to jump start a non-manipulative idea but never to sustain it. Modern advertisers can't pretend to think I am legitimately ignorant to the existence of carbonated sugar water. They're obviously sustaining an otherwise unwanted behavior in the public via manipulation. Theres no protection of free speech when theres a concentration of megaphones "shouting down" (via the most possibly advanced techniques in psychological manipulation) anything but one particular idea.
