I'm gonna ignore the first part because I've found on the internet people don't agree on what "free markets" mean.

For the second part you don't need a business to be free. As a simple counterexample: I wouldn't say that human ancestors hunting and gathering in the savannah weren't free (they had literally no governmental limits) and it would take an absurd stretch to say they owned a business.

You're misunderstanding or strawmanning. You don't need a business to be free, obviously, and no not everyone that's free has a business (???). But that's different from being forbidden from making one.

The concept of a business can only exist within the context of a myriad of laws (property law, contract law, etc) all of which require violent enforcement or the threat thereof, ie reduction in personal liberty.
