A mindless meld, perhaps. My apologies. Seems pretty close to me, though. You don't mention front or rear, so I'm guessing this advice applies to either.
If you follow my rotation recommendations, this will never happen in front.

Well, a thinner tire will have lower rolling resistance. If rolling resistance is a high priority for you, you should buy thinner tires to begin with, rather than starting out with thick tires and counting on them to wear thin.

They don't wear at the same rate front and rear, nobody says they do. If you follow my recommendation, when you replace a worn out rear with the tire that was on the front, that tire will likely have lots of life left in it. Tire consumption will be [exactly] the same, only you'll never have to ride on a worn-out front tire.

The concept of rotating tires rear to front only makes sense if you are going to replace tires in pairs, but there's no good reason to replace tires in pairs unless you run a different type/size front/rear...and if you do that you wouldn't want to rotate them either!

I don't think it's silly, do it myself sometimes, though since the passage of bottle deposit legislation here in Massachusetts, it's much less of an issue than heretofore. Also, most of my riding is on bikes with fenders, where tire wiping isn't possible.
