I didn't know you wrote it. Nice job. I figured whoever wrote it was speaking in shorthand, but I wanted to make this point clear for libertarians who tend to take an absolutist stand regarding private property.
I've had many debates with Libertarians, and know about their 'absolutist' stances. But when the question, "why should man care whether or not another man owns property.....or even lives, for that matter?" is pursued to the first principle, Libertarians {or at least those I've debated} jump ship. They have no source for moral ethics.
