correct, the Early universe didn't have to be, and probably wasn't, contained in a single physical 3D potion

Actually only certain types of particles can't occupy the same place. By the time the universe cooled down enough (ie expanded enough) to have hadrons there was enough space for them.
Think of it this way. Can 2 photons occupy the same space? How about 3? How about 2x10

The early universe wasn't the matter you see today. Heck most of the universe today isn't the matter you see today. Even so we know we can pack hadrons pretty close together already. But the real point is as energy density goes up we are not limited to the same properties of something like a neutron star or even a hypothetical quark star because the Energy of the universe is in a form where it does not have the same spatial restrictions that bosons have.
