Rooftop solar, nuclear, coal, oil, hydro - literally NONE of this matters. The whole thing about proof-of-work is that it serves as a way to prove that a particular miner spent some amount of money (in the form of energy costs) validating a transaction. As the value of Bitcoin increases, then, it means there is more incentive to throw energy at the problem, because the reward you get for mining (or, for that matter,…
The issue really comes down to that some people think its a waste of energy and some people do not. Im in the do not think its a waste camp. And as mentioned above, the hash rate is not an infinite black hole, it levels off as the price levels off regardless of userbase.
No, that's not what I'm talking about. I'm making no judgment at all as to whether validating transactions is a good use of energy.

Exactly, and your statement here 100% proves my point. Since the total number of Bitcoins is fixed, the only 2 options are (1) "the price levels off" as you put it - but the only way (long term) for the price to level off, when supply is restricted, is for demand to eventually wane. The other option (2) is for Bitcoin to eventually become a sizable portion of the financial system, in which case it's energy demands will grow proportionally.
The point I'm trying to emphasize is that Bitcoin backers' position is not possibly consistent: either Bitcoin becomes widely deployed for actually facilitating transactions, in which case its energy use grows proportionally, or its energy use plateaus, in which case it means usage of Bitcoin will have plateaued as well. There is no middle option.
