Space Elevator too ?

Once the materials are good enough and can be produced economically in
the quantities needed, why hell not? In the long run it would be a lot
better than chemical propulsion.

If you are talking about a space elevator for Mars, materials are not
really a problem. Mars' lower gravity means existing materials should
do. Phobos is more of a problem. Not a show stopper, an elevator
anchored away from the equator could be done. Still Phobos is very
inconvenient.

The real reason why we aren't developing a Mars space elevator is that
the traffic between Mars and space isn't high enough to warrant the
investment.
