Everywhere but Earth is really inhospitable, but if it were up to me, I'd pick the Moon first, then Mars, then some asteroids, then way down the list — after we've got space industry sufficient to make planet-sized mirrors — then I'd pick the planet where the surface-level condensation is lead vapour in an acid pressure cooker.
Okay, asteroids presumably make economic sense due to mining potential, but otherwise - why the hate for Venus? What's so special about being on the surface of a planet? Just don't go to where the lead vapour is, enjoy the cloudy view from 50km above the surface instead.
Might be a monkey brain, but the mere possibility of falling 50km through crushing boiling acid is the kind of thing that'll stop me getting to sleep. More so than a deadly vacuum on the other side of a wall.
Yeah but iirc because of atmospheric density it's not crazy to build a floating habitat. At least no crazier then the tech required to get a crew and equipment to Venus in the first place
1) getting enough stuff out of Earth's gravity well
2) getting a reasonably self-sufficient population for survival and manufacturing of survival goods
But once you get there, the lack of a big gravity well makes this a lot easier. Low-G or zero-G is a lot easier to move stuff around at the small scales. How much could I lift on the moon?
I'm torn between a moon base and doing enough near-earth asteroid captures to build a space hab. Political support would probably be behind the moon base first, but a space hab built from captured asteroids might be cheaper.
Anyway, once you get a big enough base in space and some manufacturing, build a couple orion pulse nuclear ships, or some nuclear thermal equivalent to hop around the solar system quickly. Then we can probably start mining high value asteroids.
Then Mars and Venus start making sense.
Maybe we can find a closer brown dwarf than Proxima.
The one big thing that Venus has, and every other option does not - is earthlike gravity. That is a big deal, so I am all for exploring options of terraforming Venus to remove that acid somehow, because despite as Space enthusiastic as I am - living inside hot acid clouds is also not my dream.
