Also, in reference to your Madison quote, in The Federal Papers he expressed the fear that if the majority of Americans didn't own land then they would vote to take away the property rights of those who did. His solution was "extending the sphere", aka making the country large enough so that everyone could own land. That way the government could give away "free land", but that once individuals already owned personal land the government wouldn't have to take it away in redistribution programs or whatever. He was never able to come up with a longterm solution, but he recognized that it was a fundamental problem that could eventually destroy that republic.
