UNfortunately, Ironman, as described in the article, does NOT represent capitalism, private property, or individual liberty. He represents, and champions the interests of the ruling politicians, bureaucrats, and corporate cronies who make up the "military-industrial-Congressional" complex.
His ways of acquiring wealth have nothing to do with the operations of the free market, finding opportunities for profit by fulfilling demands for some goods or services, and earning money by people's lives easier. He instead "earns" his wealth (stolen, in any event, by the legalized theft of either taxation or inflation) by providing an organized kleptocracy (the US government) with means of killing and maiming people who resists their predation and occupation.
Whatever this is, Ironman is representing a type of politics which has far more in common with the mercantilism and piracy of the old European empires, like the British, Spanish, Dutch, and Spanish, or even the military despotisms of anicient Egypt, Persia, or Rome, than anything that advocates of the free maket would recognise as "capitalism".
Because "capitalism" is often blamed for wars caused by, and profited through the political and corporate/media/financial elites whose activities have NOTHING to do with free markets or genuine entrepreneurship, and indeed severely disrupt the rule of law, integrity of money, and sanctity of private property which forms the indispensible basis for a free market, Ironman is a fictional character which is NOT helpful in the defense of liberty!!
PEACE AND FREEDOM!!
