I'm a libertarian and actually agree with this. And most libertarians would agree, I think, although the anarchists are a very vocal minority.

There has to be a framework of law and order and some kind of government that provides it. I'm a minarchist, and I think anarchists are wrong. Power abhors a vacuum and if you had no government at all you'd just be taken over in short order by a government you don't want, from within or without.

Capitalism works when you have laws and protections, regulation that provides a fair and level playing field, courts where grievances/contract disputes/etc. can be addressed, etc.

A lot of regulation that exists harms the market because it's bad regulation, or overregulation, but that doesn't mean regulation is itself a bad thing. I support sensible environmental regulation, for example. It's necessary.

I'm only on the same team as the anarchists at the moment under the libertarian banner because we all believe in capitalism and want to move things in the same direction, toward less government and more freedom, lower taxes and spending, freer markets. But there would come a point where we'd have to part ways if we started getting what we want past a certain point.
