That was a sensible chuckle indeed... but then it also made me realize that grabbing things IRL _moves_ them, not _resizes_ them. Nothing IRL really resizes.
So while it makes a lot of sense to grab inside the object to move it, IMO it actually makes less sense to grab _inside_ the object to resize it. (Imagine the reverse argument -- IRL you can actually grab the middle of the plate to move it, but if grabbing the middle of the window resized it, that would also be very bad.)
I've been trained to grab the edge to resize windows. So I wouldn't try to reach so far inside the rounded rectangle as OP, although it doesn't invalidate their entire argument.

A few things sorta do.
If you want to increase the size of saran wrap or aluminum foil, you grab the edge and pull. Same for increasing the size of toilet paper before tearing it off.
When you want to stretch your fitted sheet onto your mattress, you grab the corner and pull to stretch it over.
When you want to make your pizza dough larger, you toss it above your head in a circle, so I guess that one doesn't really match the macOS gesture, I guess you should be spinning windows to make them bigger.
However, when you're doing other baking things, like placing fondant or a pie crust, you do stretch from the edges some.
