On the contrary, capitalism is anything but natural. It is only a propaganda that makes capitalism good thing. It was never good. Today capitalism is in its final, ecocidal phase, since the big corporations would rather destroy the planet than miss a handfull of dollars more profit. Karl Marx proved its destructive nature scientifically while he was trying to save capitalism as a system. You should read his works, it doesn’t hurt at all. Or at least listen to the professor Richard Wolff.
