It's not just mathematical scaling, it's deeper, into human nature, just like having a small party with close friends can never be simply replicated with having a large party with close friends, because you just can't be "close friend" with lots of people.
There is the fact that the smaller a group is, the more tight-knit it can be while the bigger it is, the more faceless people become. There is also the fact that the more people you have, the more chances there is that "something happened", and the more people there is, the more each one can feel that someone else can fill up for them.
The more people are, the more there is chances of some not getting along with others, and conflict management can be a pretty heavy burden (I'm not talking about just about drama queens, but about all the low-key disagreements which can accumulate and spoil the fun). Also, there is always subgroups of people according to affinity, which tend to be typically about 5-10 in size, and the more people there is, the more these subgroups takes over the interest of people instead of the larger one.
Logistic is hard because we're managing humans, not merchandise, and humans are not scalable. We are a diverse lot, so each one has a different treshold, but overall groups of 20 work much better than groups of 40. Downsizing raids is actually one of the few changes from Classic that I see as entirely better for the game.
