Space colonization will make room for many billions of people in the solar system. Of course, population growth must slow down somewhat, as the number of people cannot grow faster than new habitats are built.

I suspect that ZPG will simply happen of its own accord.  When having many children is less desirable than having none at all, the population problem reverses, as it has in many countries already.  Space colonization?  Not soon and not in any substantial number when it starts in earnest.
