There was an attempt at this with prescription drugs. Encourage patients to take generics by forcing a larger amount of cost onto the patients in the form of higher copays. Pharma companies realized and started giving copay vouchers (still charge insurance more, but short circuit the patient incentive). When that loophole got tighter they formed charitable foundations to give the vouchers instead. I'm not disagreeing with your points, per se. It's just amazing what entrenched interests can manage.
