You have a really weird set of arbitrary lines in the sand. So it's totally OK for a single doctor to make huge profits off the NHS when they charge patients for treatment, but if those doctors form a company to share the load and amortise overheads, then suddenly it's a terrible evil that must be forbidden? And don't get confused by simple word changes: when a doctor turns up at a hospital and does work in return for a large paycheque he is very much "charging a patient for treatment". The fact that the charges come in the form of taxes and take a long route to get to the patient's wallet doesn't alter the fact that the money comes out of the patient's pocket and ends up in the doctor's pocket!
