Scott, youre getting as good as I used to be at finding strangeness... I can understand a plumber being cool with us and putting a waterline out for us to bond, but I'd think a cap would be favorable to the hosebib on the end...

There's no minimum or maximum pipe size in NEC 250.52(A)(1) nor is there a material specified, only that it be "metallic".
The clamp thingamajig is pretty creative, too
Many inspectors in this area won't accept a capped pipe as part of the Grounding Electrode, because it may contain only trapped air. As lame as this thing looks, it might have been done in response to a correction notice.
Can a plumber put a hose bibb indoors with no drain?

And they do this, why??--It's the pipe that conducts electricity; water is actually a rather poor conductor. It conducts enough for the few milliamps it takes to kill someone in a bathroom accident, but not enough to seriously be considered as part of the grounding.
In fact, pure distilled water is actually a reasonably good insulator.
