"False" has a very different meaning than invalid (Which it isn’t anyway). Is it intentional, to try make logical reasoning look somehow dishonest, to try to inhibit folk using logic? Do you dispute capitalism is all about looking after our own self interests at the expense of others?
The supply chains you mention are far from perfect, in fact breaking down all the time as various participants get made bankrupt or just get their fingers burnt, or even hang themselves in a barn. The biggest players always take all the winnings. Would you volunteer to be the five year old kid working in a mine in Congo? What is cool and fair about that?
Besides now we know the systemic result is a burning planet, because all the energy fuelling it all has to come extracted from the planet, which is destruction by definition, the constant conversion of things nature created to heat.
So the arguments of whether or not capitalism is morally right or wrong are actually superseded, by now the question of what is survivable, absolute selfishness, or absolute generosity?
