How can the far side of the moon be higher than the near side without shifting the center and making them equal?

Same way that the northern hemisphere of Mars is a lot lower than the southern hemisphere - crustal thickness.

The far side has a thicker crust than the near side, apparently due to the effect of earthshine from the molten earth on the near side early in the Moon's history.

Density does not have to be uniform.

That was phrased really oddly. I think essentially he means, the far side has a larger topographical variance.

I’m no astrophysicist but centrifugal force seems like a plausible explanation.
