So there is a problem to be solved. Great!

The history of human spaceflight is pretty much: Problem -> Difficult to find solution -> Solution leads to better spaceflight -> Solution leads to better life for humans on Earth. Then repeat that cycle for each new problem.

Think of the new medicine and hospital protocols that are waiting to be developed as biologists explore the solution to this problem.

Couldn't agree more. But I'd recommend solving the problem before shooting ten men and ten women into the Martian regolith forever and telling them to make babies.

Alternatively, it's not the scale of problem you try and solve fifteen timeslipped minutes and (at least) eighteen months away. We're not even sure what the shape of a solution even looks like, apart from "Generic Future Technology Tree Numbers 4 through 90". Mastery of bioengineering would probably fix it, but it would need to be desktop science, like 3d printing. We are not anywhere near that - mostly because we don't have things like "generic bioreactors" that can grow organisms like a universal womb/seedbed/strata/media.

I recognize human advancement comes with sacrifice. But human advancement also comes with prudent decisions like "don't built the village in the lava".

Indeed, and that’s why we’re starting sensibly with a lunar colony…

I think you’re also exaggerating those issues considerably.
