It's hardly an oxymoron. It just competes with established ideology. Ideally, there is no Conservative ideology either ( it advertises itself as pragmatic and empirical ) but this arguably requires too much work in political spheres to hold up. "Free" markets vary by degree - nobody says there must be no rules, no rule of law. Taking it back to Adam Smith, he's simply arguing against Mercantilism. So any rules that entrench an incumbent could ( possibly ) be considered a degree of Mercantilism. But the context matters because of specialization and inertia/momentum.
