Okay, cool, I can see where you're going with this. I wouldn't exactly agree, because all of these things are stuff you can easily opt out of, but I thought you were maybe suggesting something like "the borrow checker has overhead" which I would take more direct issue with.

(and yeah, the opt out question gets right to what you're saying about "naively used", I saw "unavoidable" but you're not actually saying it's unavoidable.)
