Or he prefers compulsion over the free market and slavery over liberty. If he is truly libertarian, he'll leave the businessman alone, choose to personally not do business if that's what his conscience dictates, and leave the government out of the equation.

Libertarianism - Wikipedia, the free encyclopedia
"
Libertarianism (
Latin:
liber, "free") is a
political philosophy that upholds
liberty as its principal objective. Libertarians seek to maximize
autonomy and
freedom of choice, emphasizing
political freedom,
voluntary association, and the primacy of
individual judgment.

I think I prefer Wikipedia's version.
What is The Libertarian Party?
"Libertarians believe in the American heritage of liberty, enterprise, and personal responsibility."
It's not that much different to what the Libertarians say themselves.
So, it's about liberty which is about not being controlled by the government or others.
However, I'd say, like any right, there are limitations. Many freedoms conflict with other freedoms, many desires of free will conflict with other desires of free will. Who is there to mediate between the two? Should it be a free for all? No, that's Anarchy.
Libertarianism would be maximum freedom for all, which requires government regulation in order to achieve this.
So, I'd say liberty is the ability to walk down the street, go into any public business and conduct business there. If I am denied conducting business the same as everyone else, then I don't have liberty.
If I am denied service in a shop because I am black, or because I am a woman, or because I am gay, or because I have a deformed part of my body, or if I am denied because of something I was born with, then I am not free, I don't have liberty.
anarchy: definition of anarchy in Oxford dictionary (American English) (US)
Anarchy

nonrecognition of authority:"
This is what some people believe is Libertarianism. It's not.
