It doesn't have to be the same doctor, but anyway a doctor is not a bureaucrat and buying medicine with a prescription is something that only involves private parties (unless you want to be reimbursed by social security when it exists of course, then social security is obviously involved and it might be public).

If you're advocating for the end of mandatory doctor's prescription for all medicine that's your right, but it's rather doubtful that it would be an improvement over the current system.
