The neutral is a current carrying conductor, but at "ground" potential or close to.
By using the EGC as the neutral, you have neutral current on metal attached to the electrical system. It will and has caused fires and there is the potential for a fatal shock.
For example you use the EGC as the return neutral. An electrican is working on a circuit and opens the neutral and gets a fatal shock.
