I consider myself to be economically liberal in the "laissez faire, laissez passe" sense to a large extent. No government should pick winners or losers, no government should protect uncompetitive businesses.

But I believe that the government must protect the free market against capitalism's inherent tendency towards monopoly, and that likewise, it must protect consumers against exploitative business practices (which arguably, a properly competitive free market could help achieve).

I'm pretty sure this is the standard belief of most libertarians. People just keep conflating libertarian with ancap.

In theory libertarians might be into that, but I don't exactly see prominent libertarians calling for antitrust action. An actual political group that is ostensibly pro-market but also big on making sure rules are followed to keep the market in optimal condition are German ordoliberals.
