I am in favor of freedom to reject buying insurance if you can answer one question for me. What happens if someone rejects buying insurance but gets seriously ill and is brought into an ER for help. They can’t pay. The hospital can’t turn them away. Who pays the bill? If they are illegal, I would say treat the emergency and then ship them out of the country. What do you do if they are legal citizens?
Health care is a private service business. Insurance is a private service business. Free or government subsidized health care or health insurance are not constitutional rights. It would be unconstitutional for the government to pay for private services for individuals. It would also be unconstitutional for the government to force individuals to subscribe to any private service business. Furthermore, using the tax code for social engineering is unconstitutional.
If a local community, church, charity or group of doctors, etc, wishes to provide a local hospital, emergency room or clinic for poor people, more power to them. But it’s none of the federal government’s business.
