Betty and Veronica don’t need to know of one another.
Right, then blacktrance’s complaint holds that you’re not just adding up the utilities of all the agents in the world, which is a condition of utilitarianism.

PhilGoetz was trying to show that to be correct or necessary, from some first principles not inclusive of simple assertion of such. Had his point been “average utilitarianism must be correct because summation is a condition of utilitarianism”, I wouldn’t have bothered replying (and he wouldn’t have bothered writing a long post).
Besides, universe is not made of “agents”, an “agent” is just a loosely fitting abstraction that falls apart if you try to zoom in at the details. And summation of agent’s utility across agents is entirely nonsensical for the reason that utility is only defined up to a positive affine transformation.
edit: also, hedonistic utilitarianism, at least as originally conceived, sums pleasure, rather than utility. Those are distinct, in that pleasure may be numerically quantifiable—we may one day have a function that looks at some high resolution 3d image, and tells how much pleasure the mechanism depicted in that image is feeling (a real number that can be compared across distinct structures).
