How exactly could using a red as a ground hurt anything?

At some other point in the circuit, somebody may someday decide to connect a
hot conductor to it, perhaps.

The absolute worst senerio is that someone in the future will be working on
the circuit and find the red isn't hot like he expected, and that the ground
is missing. If he isn't bright enough to put the two together (and the
green tape has fallen off the red wire) he will have to fall back on your
suggestion, but there is no way any harm can result.

I'll agree that it's unlikely, but as they say, never say never. Categorical
statements are always false. g

In any event, whether harm can result or not is moot. It's specifically
prohibited by the NEC.
