I would have guessed you could do relatively cheap tests (very relatively) of this sort of life at the bottom of the Pacific. You wouldn't have the same viewership, though.
What would people do on Mars? I just can't imagine wanting to live there.
I get that there would be a lot of work building and maintaining basic life supporting stuff. But other than that, you're stuck - forever - in a tiny environment with not much to do. You can't go outside, or you'll die. I suppose you can plod about on lifeless landscape in a heavy spacesuit, but that's gonna get old real fast. You can play boardgames, I suppose, and download stuff on a delay from Earth. It sounds like a terrible dreary life.
But living a desperate life, dying poor, alone on a planet of billions, forgotten? That, sir, is scary stuff!

Sure. But the problem isn't that the Martian surface is so inhospitable to human life. It's that it's really, really far away. And the cost of moving materials to Mars is enormous. And we don't have a whole lot of vehicles with which to do that (or, at this point, any). And cost of creating said vehicles is enormous. And we have no practical experience trying to maintain any sort of human habitation beyond Earth orbit (and even the ones we have are in no sense permanent).To be honest, the surface of Mars has more in common with the land surface of earth than it does the floor of Earth's oceans.
Without the direct backing of powerful nation-states, flush with resources, and capable of massive borrowing/fiating currency into existence, a project of this scale is impossible.
Nonsense - there are individuals who can afford the 6bn the project is estimated to cost, let alone corporations. This absolutely does not require a nation.
And the broadcast of the biggest show on earth is not "coffee mugs". It's incredibly large amounts of money.
