Bad extrapolation of analogy, but still - how convenient that you decided to focus on the lower bound. How about the high bound? Can a car go trillions of miles per gallon? Because Bitcoin block can contain trillions of transactions every 10 minutes.

You can, it’s just not useful.
So? A running car consumes gas even when it's idle. My parents used to measure MPG at every tank refill, which was a combination of miles, idle, braking, etc.
We can certainly take an average of transactions to get a reasonable number for watts/transaction.
> no, actually, it's an opinion.
... which was stated as fact.
