LEO is proven; there's a need, thus a market, and the science is sound. Mars, not so much. No need, just dreams for an irresponsible solution to Earth-bound problems that still will need solved. The lack of air on Mars can be solved; we could terraform it, over a long time, create the air needed to support life. The lack of a planetary dynamo and magnetic shield from radiation probably can't be solved. What is the difference between tin cans in LEO using centripetal force for artificial gravity and tin cans on Mars? One is a lot less expensive, and if something goes wrong, there is at the very least a possibility of escape or rescue. Mars is somewhat of a death trap. So no doubt Musk cares about space stuff, which has been profitable for him. I'm just not sure he's really serious about Mars or if it is his version of a reality distortion field. It really looks like a monorail to me.
