thru your body to other components or anything else
you could possibly touch at the same time.
This is why all the chassis on all components have
to be tied to safety ground, not neutral.
The safety ground IS neutral. It's tied to neutral at the service panel. If it were not, it couldn't serve its only function, which is to be a return path for faults on the AC mains' HOT lead.
But let's get back to your 650 volt example.
That 650 volts is derived from the SECONDARY side of the power transformer. How can the AC safety ground possibly be a return path for that 650 volts? There's no DC path between the primary and secondary windings of the power transformer.
