Austrian economists resemble Jehovah's Witnesses.

A blogger, while praising Austrian economics and the Ludwig von Mises Institute as his motivation for running a marathon, writes:

The institute has a special place in my own heart, for without the vast library of historical and economic literature that it generously provides online for free I wouldn’t have had the opportunity to pursue an independent education in economics.

So why, exactly, do Austrian economists have to give their literature away, like Jehovah's Witnesses and similar religionists? Because nobody wants to buy it? Or in other words, because the market rejects its production as a waste of resources?

I notice that the non-Austrian economists who write those Freakonomics books don't seem to have that problem.

I also notice that the two other sources of libertarian thinking in the U.S., Ayn Rand and Robert Heinlein, never had to give their novels away. Those novels stay in print, long after their authors' respective deaths, because of market demand, not because of a private command economy which keeps producing this literature in defiance of market signals.
