I'm not entirely sure I follow your argument, but you seem to be claiming A implies B, where in fact A is true and B is false.

> Open-source also means: The entire planet's population is the pool (of developers).

This is currently true, even when closed source software also exists. Or at least, getting rid of closed source software won't make it significantly more true than it is now.

> As soon as there is a real need for something, and somebody in this world is willing to work on it (for whatever motivation), this piece of software instantly becomes available to the _entire_ planet, without barrier (no price to pay, no payment method hurdles).

This either is not currently true, or is not as powerful a property as you claim.
