I think we disagree on the definition of force. I don't think of force as just the power of law, but also the power of size and power. A natural monopoly could, without any government interference or help, exert a lot of the same coercive tactics a government-supported monopoly can. With a large enough size, a natural monopoly could make the barriers of entry for any potential competitor so insurmountable that it would have the same effect as making competition illegal.
