To be fair, money as a signalling mechanism is a useful tool, but it can't be as neatly separated from politics as libertarians believe. Most politically relevant agreements are either made behind closed doors or benefit from insider information, so their signaling does not improve market efficiency for all involved - just the well-connected clique; and the "creative accounting" by major firms is responsible for distortions in what companies are being considered efficient, again allowing a small oligarchy to gain market advantages even when nominally participating in a free market.
