[Star Trek voyager] why can’t they copy the doctor and have 2 doctors ?

When they start using the mobile emitter, why are they transferring his program and not running two copies?

Ethical concerns, I'd assume. They're clearly *capable* of making a copy of the EMH (as shown in that one episode where they lose a backup copy that's found centuries later by an alien race) but possibly unwilling after they determine the Doctor has achieved sapience and recognize him as his own person and not just a simulacrum.
