That's pretty much the most irrelevant thing I've ever heard.
Fistly, I don't think anyone has ever seriously proposed building electrical transmission lines out of superconductors. It's just logistically ridiculous to cool that large of a system.

Secondly, how the heck is nitrogen not being a renewable resource relevant? It's probalby the most abundant resource readily available to us, the atmosphere is 80% nitrogen. And how is that not renewable for the purpose you're talking about? The losses for liquid nitrogen from cooling colling superconductors will just end up back in the atmosphere, were we can just grab it again, it's not like it disappears.

I'm not saying you're other points are valid, just that adding this one seemed pretty silly.
