It's more sensible if you plan to keep a bunch of people there with constant supply from Earth. Elon wants to build a *self-sustaining* city on Mars. There isn't any other choice of location, be it man-made, or in the solar system:
- that has enough resources, atmosphere, gravity, water to allow a non-trivial population to survive without help from Earth
- that is hospitable to life
I suggest you watch his previous presentation where he talks exactly on why Mars is the destination, and not somewhere else.

Atmosphere is possible in man-made structures. Gravity can be simulated in man-made structures. I don't believe water is particularly scarce, and it is reusable except for when it's used to create fuel. With the Sun + plants a lot can be done. Mars, on the other hand, has low gravity and is far away from the Sun.
