Implicit in moore's law is that cost does not increase in the same way, if not prices of chips would also be doubling. Something more analogously sounding would be the decrease of cost per transistor.

The number of transistors is also not dependent on a single thing, it can be argued many macro events contributed since the 80s, the VC model for chipmakers in SV, the rise of the internet, going fabless, rise of mobile, innovations in fabrication technology.
