But make no mistake about it: it was not a free market of the kind envisioned by Adam Smith. That was more a vision for the burgeoning first industrial revolution when we were in the transition from feudal guild markets still situated in an agricultural economic base. Smith himself warned of the dangers of large corporations taking over and monopolizing the marketplace.
If we accept that capitalism was a functional fit for the era, we must also admit that it no longer fits for the emerging era. It's time to free the market yet again, this time with free goods and services, i.e., in terms of marginal costs, not fixed costs. As to who finances the latter, it was discussed in the book chapters in previous posts.
