In fact, should the human race shrink significantly [due to antinatalism perhaps], without societal collapse, the average utility of a human life should increase.

Why shouldn't having a higher population lead to greater specialization of labor, economies of scale, greater gains from trade, and thus greater average utility?

Resource limitations.

There is only a limited amount of any given resource available. Decreasing the number of people therefore increases the amount of resource available per person.

There is a point at which decreasing the population will begin decreasing average utility, but to me it seems nigh certain that that point is significantly below the current population.
I could be wrong, and if I am wrong I would like to know.

Do you feel that the current population is optimum, below optimum, or above optimum?

Because of the law of diminishing returns (marginal utility). If you have a billion humans one more (less) results in a bigger increase (decrease) in utility than if you have a trillion.

Whose utility? The extra human's utility will be the same in both cases.
