I don't see it being productive or possible.
The few people you would have to send would have to be highly trained in maintaining the environment they would be living in...which, to be frank, prevents most of us (myself included..unless they need SPACE JUSTICE!) from even being applicable for going.
You would have to send constant supplies given the lack of water (or at least- readily available water?) and oxygen on the planet. I doubt we have the ability to terraform even a small patch within some sort of protective dome, making the ability to grow plant foods for the long-term a notable problem. Just sending the supplies over to them would be an expensive venture, and would take time to reach them. You'd have to maintain a strict rationing system and just how would these people run themselves? Would they still be tied to national (Assuming U.S. because 'Murica'.) law?
Then there's the concept of reproduction. There's a limited amount of available partners and the ever-limited amount of resources. Even having a hundred people go to the colony is a limited gene pool, and that's without accounting for the potential for families/multiple people from one bloodline, and other non-reproductive relationships. Assuming the colony, for some reason, doesn't expand in size and resource intake to accommodate more people...? Don't see it as a long-term prospect, so-
Personally, I prefer the Earth. *dives into tank and flies off majestically into the sunset*
Mars is boring. I would like to land on the sun
