The current on that ground will be on every ground wire in your house.

Not exactly true. It will just be on the grounding conductor going
back to the main bonding jumper, that one circuit. (unless you have
bonded that EGC to other circuits down stream of the MBJ)
In normal installation these are star wired.
It still can present a hazard and it is still a 250.6 violation.

I agree it's a violation but the hazard part would require a couple of
other faults, wouldn't it?

Just one. An open EGC.

If a ground carries current but is at ground potential, seems like you
shouldn't get a shock. If the ground conductor was broken anywhere on the
path back to the main panel, all the connected grounds would be hot. But
then your light wouldn't work, you'd know you had a missing ground.

The hazard would still be there with the light turned off.

***Ground at no time should carry any current if it dose it means that some
how you ground and neutral; is ****ed up!!!
