I don’t think they could actually stop such a technology from being deployed on earth in such a scenario. Nor do I think they would really object, it seems doubtful to me that they would all want to go to mars, and for those that don’t, trying to prevent it’s use is counter to their interests.

The technology to allow them to live the kind of life they would want on Mars would also greatly decrease the human impact of the climate crisis applied to earth. A mars colony fundamentally requires the ability to insulate an entire city, to ultimately civilization, from a climate more inhospitable than we could render earth even if we burned every scrap of coal and oil in the ground, and a billionaire would probably want more than just that bare minimum functional civilization to live someplace.

Ive ended up making one of these myself lol. When I came over to lemmy from reddit around the third party apps thing, I tried to create a community for the game Spore (a bit niche these days, but it had a small but active reddit community that was fun, and I hadnt really realized yet that the small size of lemmy would mean individual game communities wouldnt really be viable except for a handful with very large playerbases).

Ended up posting a few things I made in game myself, and I think I got one or two posts from other people, but nobody else really joined it and eventually I moved on to other games again (I tend to go through my library in cycles of a few months).

I may come back to it if I get back into that game someday, and I am still active on lemmy, so if someone started trying to use it as a space to spread hate thinking it abandoned, I am still around to remove it, so for the moment I dont think mine at least poses a problem per se, though I suppose if I ever tire of the platform as a whole I’ll need to either ask around if anyone else wants it or else look up how to close it/ask an instance admin to if that’s needed.

Colonists aren’t really immigrants though, their intentions aren’t to join an existing, foreign society but to create a new one or extend their existing one into another area (and in cases like the Americas, also act as an invasion force of sorts to push out existing people).

One must wonder about male and female invertebrates next

That variety of Sardinian cheese that contains live maggots.
