I repeat it: Cross chaining leads to chain rub on a front derailleur (a negative) and this is eliminated when there is no front derailleur.

Sure, that's a benefit of a 1x drivetrain, but there are other ways to avoid chain rub -- such as setting up the drivetrain properly, using the FD "trim" feature, or running an electronic drivetrain. I love hearing my FD trim itself automatically as I shift the chain across the cassette.
Chain rub is a non-issue.
