Libertarianism is a cunard. It's a petit-bourgeouis fascism that wants to use money, as opposed to the state, as a means of control. It's the favored ideology of reactionaries who've internalized the power complexes of their masters.
My friend said something valid that I'll throw in here. "Perfect is the enemy of the good".
Besides, a free market and an egalitarian society are not totally contradictory. You can be partially free and partially structured, which is the most likely of all options because absolutes are extremely rare.
