I don't know. A lot of this Lunar, Mars or Venus colonization stuff cannot be logically reasoned for. I think we have conquered all the Everests, we have made it to the poles and now we need another goal beyond our reach to strive for regardless of its actual worth.

Maybe if you harness a huge amount of earths resources you could make it there but bear in mind that we haven't launched a living human beyond the Low Earth Orbit for decades. The furthest point a living person has been from the Earth and returned was around 250K miles and that was Apollo 13 back in 1970. Jumping from where we are now to a manned capsule floating above Venus is pretty nuts.

Its fun to think about and plan how it could be done and use it as a measure for how far we are from it but that's completely different to strapping a bunch of peeps into a can and launching them toward an unforgiving exile.

Look at the excuses provided for doing it:

a vital resource located on Venus, mass over-crowding, nuclear apocalypse

How vital would it have to be exactly that we survived this long without it? Mass over-crowding? It would be cheaper and easier to have another world war, that would gain a bit of breathing room for a while, far more likely we will descend into violence with assured success for the survivors rather than join in mutual peaceful sharing of valuable resources with the minuscule chance of success for a few. Nuclear apocalypse! Fugetaboutiitt.

Have we started living in death valley yet on a large sustainable level? What about the polar regions? What about under the ocean. All of those places are more habitable than a planet we have not evolved over millenia to survive on. 9/10th gravity might just be enough to postpone osteoporosis for a few years.
