Humans now give birth by laying an egg, it still takes 9 months to hatch, how is society now different?

Human eggs are about the largest single cell humans produce, about 0.1mm in diameter.
But human eggs don't provide nutrients to the fetus, they grow the placenta to do that. So over all the entire process would have to change to something probably impossible. Consider the ostrich lays the largest egg now, and ostriches are larger than humans. Humans that would need a far larger egg.
The math just doesn't work for humans to have a hard shell egg.
