When you say "all that has to happen is..." you are glossing over what sounds like a good century's worth (or more) of research into simulation and computer system design.
You make it all sound very simple. If it is so simple, why hasn't anyone done it? It's not just a lack of computing power, it's a lack of simulation techniques complex and complete enough to pull it off. This stuff isn't right around the corner, it's at least decades away--if not longer.
Well, to be fair to Mars:
we are talking about the world of 2100.
