Great overview. I just wonder, if it was really necessary to renumber all the NG regiments in 1917. I mean, we got through the Civil War without too much confusion due to overlapping state numerical regimental designations right?

I'm hoping you're being sarcastic...

Actually I'm not, but perhaps I've simply missed or not read enough where this became a problem during the Civil War.

It was a major issue during all the wars where we used volunteer regiments. Written improperly, the 15th NY could be NJ or NC or NV. Stating the "15th Regiment" could be just about anyone. It organized everything to a far greater extent

I understand the basic admin headache... But do we have actual examples where it caused significant problems? Orders issued to wrong unit in a battle or campaign, or pay not getting to a unit, etc?

Sure. But did numbering have to follow that? It's not like we're the only country in the world that had different numbering schemes and eventually standardized training and ranks. Others... didnt seem to find renumbering necessary...
