from wishful thinking. Colonization of any planet is currently
way beyond our capabilities - it's not even clear that humans can survive
on any planet other than earth using only in-situ resources. Even
Mars, which would be the most likely candidate, suffers from the lack
of a van allen belt and thus the radiation at the surface pretty much
precludes any substantial settlement by humans.
There is no fundamental law that makes it impossible for human beings to
colonize other planets, and I did not state that this will take place
tomorrow.
I never said that. I did say that there is no known, or anticipated
technological advance that will make Mars habitable sufficent to support
more than a few people at any one time. Perhaps you
have been reading too much Science Fiction?

There are 140 million babies born each year. What would it take to
transport that many people each year to another planet, and how long
would it take? And how much would it cost? And without the governments
that you lambast, who would pay for it?

Basically, we could expand nuclear massively, absent politicians, and of
course complement that with solar/wind where possible and desirable.
No, it is not physically possible given planetary resource limitations.
Completely leaving aside the considerations and costs of waste disposal.
