Maybe, maybe not. Console access doesn't have to mean complete access. The scenario I always have in my head for these sorts of things is a Computer Lab at a university/college. You can allow anyone to come up and use the machine via the keyboard/mouse/VDU attached to it, but to counter the attack vector you mention, you simply lock the computer itself away in a secure cage under the desk. That also stops the "security vector" of someone simply picking up the machine and walking off with it ;)
