I will do no such thing because I have not argued that "a free market will save us". I solely wanted to note that arguing over definitions and making caricatures of commonly understood terms ("But what does it really mean to be free?") is pointless and does not add much to the discussion at hand.
I agree, however, with the comment made by gaius: historically it is more probable that a free market produces innovation than a centrally planned economy. Not, IMHO, because the abstract entity “free market” somehow magically comes up with a solution. But rather because it allows individuals to tinker and to test their results w.r.t. the actual wants and needs of other people as opposed to assuming that the best solution can be planned and designed top down.
