When a free person buys insurance from a private company, the company has a profit-motive in remaining solvent, and the government uses it police power properly to enforce the carrying-out of the terms of the contract freely entered into. But when government uses police power to compel a person to buy government insurance, there is no profit motive, and there is no third party existing, to enforce the terms of the contract. It seems to be a most precarious venture, at best.
