The link you posted doesn’t support this claim.

> It's a natural consequence of capitalism

Adam smith was hostile towards monopolies (which your link refers to - nothing to do with price fixing although the conclusion is the same) and his critiques being very apparent throughout Wealth of Nations. This is a common opinion with proponents of free markets.

So what specifically about capitalism makes this a "natural consequence"?

Regulation is literally there to compensate for these types of issues with unregulated capitalism. I don't see how you could draw the conclusion that the thing we've tried many times and that works a lot of the time can't work.
