(V): "Even if governments were not involved... we'd still have monopolies, as we do now manipulating the market, bribing suppliers to reject competitors."

You can't stop monopolies from occurring, they will happen. Competitors always manage to overcome a monopolies stranglehold over a particular industry, unless government partners with that monopoly. A powerful business monopolising an inudstry always attracts the attention of a powerful government intent on holding onto its own power... they will either support the monopoly or oppose it.

I suppose in a perfect world there would be no monopolies. In a perfect world I would also win as many games of chess as I lose, but then I could also forget about any ambition about rising to the top. Fantazising over what life would be like in a perfect world has never improved my game.
