I would totally be down for a state but we'd still be part of the contiguous American landmass so to speak. Leaving us EVEN MORE susceptible to attack. A lot harder to attack us on Mars when you consider the weapons wouldn't have to be just long range but interstellar. That would take a considerable amount of time, research, spending, testing, failing. I just think as long as we kept our distance from white earth, let them know just enough to keep them informed but not so much they can make a move. While we develop our own weapons in secret with all the amazing minerals and resources we'd like have natural access to on Mars.
I look around and most places have their issues. Like Canada is going through some communist takeover, Mexico has the cartel deep in their government's pockets, and no way in hell would I go south of Mexico. I used to think that our people would be better off getting back in touch with our roots and going back to Africa but natives in Africa seem to have beef with us. We legit have nowhere to go that is "safe". At this point, Mars isn't looking like a terrible option... LOL
I just feel like it is too risky though. We shouldn't be the first people doing it. If something goes wrong, let that be on their hands.
