I can have

u(world) = total_lifetime_veronica_happiness + total_lifetime_betty_happiness - | total_lifetime_veronica_happiness - total_lifetime_betty_happiness |

This will compel me, on the day one, to compare different ways how I can organize the world, and adopt one that has the future where veronica gets more balloons, but not excessively so (as giving all to veronica has utility of 0). Note: the 'world' defines it's future. As a consequence, I'd allocate a balloon counter, write up a balloon schedule, or the like.

I don't see how is that at odds with expected utility maximization. If it were at odds, I'd expect you to be able to come up with a Dutch Book style scenario demonstrating some inconsistency between my choices (and I would expect myself to be able to come with such scenario).

It's compatible with utility maximization (you have a utility function and you're maximizing it) but it's not compatible with world utility maximization, which is required for utilitarianism.

That utility function takes world as an input, I'm not sure what you mean by "world utility maximization".

The maximization of the sum (or average) of the utilities of all beings in the world.
