Free abortion? For one thing the price would likely go up, not down. For another, why do you assume everyone thinks like you? Statistically more want to restrict abortion, they would condemn it. That would raise the cost. Social pressure, reputation, having to fit in the various relationships in a community to live, all these would combat the notion of free abortion. In time, no longer dependent on the government to make moral choices, society would.
Your statistics are off, warped by confirmation bias.
I don't understand you last sentence, too garbled.
