In absence of geographical distances, we can create social ones.

Isn’t this the same thing from a different perspective? I mean, the important thing seems to be how far you can travel on a full stomach. That can be increased by either moving faster or having a greater stomach.
I agree that a bigger stomach allows for a bigger range, but this is not the only effect it has—a bigger stomach also allows for survival long after there are literally no providers left, which means that there can be areas that are rich in selfish characters, and if any stray altruists do wander by, they will further feed this group, whereas with a smaller stomach, these areas will be barren, providing a breeding ground for altruists that can then lead to a resurgence of altruists, temporarily spared from the selfish ones.
