Did you know that some countries already have laws about procreation. China for one has laws limiting the amount of children one can have. Some places the limit is one child per family

So no, out lawing procreation is a very real thing.
So in 20 yrs as the article states we start becoming immortal. Wait a hundred years and what? We still won't be able colonize much of our solar system few planets and moons exist that could even be considered for colonization. We would become an infestation in our solar system to the point we would have to move out of our solar system then what live on space ships like in Babylon 5 ?
Well if our minds began melding with AI and we can could go into virtual reality, then space wouldn't really be an issue. We could spend most of our time in virtual reality and materialize ourselves in the physical world only occasionally, or not at all. We could still procreate that way, too (through both conventional and non-conventional means).
EDIT: if we really wanted to, we could even "shrink" ourselves, by having diminutive representations of ourselves in the physical world. They would be like dolls with which we could experience the world, while not affecting it. Or we could use holograms, or something equivalent. The point is, there could be trillions of "humans" living on earth without any noticeable impact on the environment.
