It's funny that you're using the word "deserve". Based on whose moral framework? I'm not sure current moral frameworks on Earth would be against colonizing the Universe if it was possible.
Its not even about deserving it. How are going to maintain a terraforming project or build habitable orbital platforms if we can't manage keeping our natural habitat habitable?
Because humans evolved on Earth and not on Venus.
If we evolved on Venus then it would be our Eden.

Is your model anywhere good enough to be able to get useful outcomes from this process? I would suspect not. I mean, we know this planet's state is partially owed to the many unique comet impacts that have occurred during it's life, are you modelling those?

Maybe projects like this would distract us from stupid tribalism ?

I don't think we can just anthropic principle this one away. We couldn't have evolved on Venus. It's valid to ask whether any complex life could.

Got it, reflexive blanket dismissal comment.

Everybody needs to watch this to understand how exquisitely balanced our planet is.

Without tectonics, is terraforming Mars even possible as a long term solution? This "Mars colonization" strategy seems like a pipe dream, no?
The lack of tectonics would only be a problem if you want your terraforming to be 'one and done'. If you admit that terraforming, even after it's 'done', will require an ongoing maintenance effort, it's simple (but not easy). Eg you can use satellites to spin up an artificial magnetic field to shield against solar wind. However, I suspect terraforming planets is a waste. Far more bang for your buck to build habitats…

It's worth mentioning that one of the more sane ways to terraform a planet is to redirect specific comets to crash into the planet. It would be "free" in the sense that redirecting an orbit is already actively being studied by NASA for planetary defense reasons. To actually terraform a planet in this method would be unreasonably affordable compared to anything else I've ever heard. edit: Plus, it's nice to split our…
I didn't think reasonable really has a definition here. The rendezvous with these comets will take centuries or millennia even if we can get out there and kick them the right way (which is much harder than arranging a miss). Only then do we start terraforming, which takes thousands/millions of years in addition. Who/whatever we're preparing the planet for probably wouldn't be "people" anymore. :)
The methods we could realistically launch into in our lifetimes would take thousands of years, not millions (but also not hundreds) [1]. Projects of these timescales have precedent in human history, usually with a healthy dose of religious zeal.

The Earth hasn't always been hospitale to humans, much less technological civilisation. Chances are, we'll have to do similar "maintenance" at home, too. (Easiest to grasp: deflecting asteroids.)
> I suspect terraforming planets is a waste. Far more bang for your buck to build habitats in space from scratch
This comes down to how biology works in zero and partial g. One of the most useful set of experiments we could be doing right now, in terms of colonisation, is putting lots of rats and whatnot in tiny space stations and letting their life cycles play out.

That's obviously the point I was making.

No, I said my _suspicion_ is that you cannot, and you're being a hypocrite.

That's about the connotations of the words "Hell" and "Eden", not about the facts being discussed.
And why did humans evolve on Earth but not Venus? In fact no life evolved on Venus that we know of.
