But neither can Mars. Most of its early atmosphere was blown away and that will continue. There's nothing we can do about the lack of gravity.
The problem with Mars is that it is cold, terminally. The nuclear furnaces have gone out. I haven't seen a proposal from the terraformers that counteracts that. You might be able to counteract it with CO2, but then that gets blown away by the solar wind. It's crazy hard to fix.
Don't get me wrong, I would love to see us on Mars. Unfortunately, the engineering and science obstacles are huge, enormous.

Yes, I agree we should go to Mars. I don't see the urgency, though. I mean, in terms of the humanity-backup situation, ten years or a hundred, doesn't really make much difference.
We would be better putting the money into energy research, and when we've got that figured out, then we tackle mars.
