I'm only saying there are consequences for concentration of relative wealth that even market fundamentalists (such as libertarians) argue against. I am not one of those. My position is complicated. I find the best explanations of market failure come from a greater financialization of the economy as a whole. Which is to say, in this increasingly programmable world we live in, there are greater and greater opportunities for gaming the system. Even startups inevitably head in this direction. Financialization is an economic gravity-well.
