Parent’s point is that economic inequality is so bad that the costs are meaningless to the ultra wealthy.

Thank you. Exactly that. Prices do not adapt to the scale that super-rich manage.

And it seems that it touched some sensible point as the comment is at -3 right now.

That does not change that billionaires are incompatible with capitalism. They have too much power, so instead of reducing costs, increasing production or providing better services they just play to be god with our resources. And they monopolize the economy, stop competition, and kill capitalism. And I think that capitalism is not that good and needs a lot of help from the government to function, but it was better than authoritarian waste.
