You are taking trends that have lasted a century at most, and extrapolating them thousands of years into the future. As long as the trait “wanting to have many children even while wealthy and educated” is even slightly heritable, not necessarily even genetic, then that trait will spread, leading to a reversal of the demographic “transition”.
I agree with your predictions. However, I was talking about why space colonization might be desirable now, rather than why it might become desirable in the future.
