Yes they do. But before that a transportation system needs to exist. Starship needs to be easily and quickly reusable and that's a necessary step to becoming multiplanetary or it will simply forever remain too expensive.

> Where does the money come from?

The goal of SpaceX is to make all of what you describe possible within or slightly above NASA's spaceflight budget as well as within the price range of a pioneer who wants to give up everything on Earth and move to Mars.

> How will we make the Martian surface habitable?

The surface will not be habitable by anyone within our lifetimes. People will live in structures that are either underground or partially buried.

> Even if getting launch costs down to 2 million as Musk stated once is possible (hard to believe, Falcon 9 is nowhere near that today)

Falcon 9 throws away carefully engineered and built hardware every single launch. It was never going to get down to those price levels. That's why you need a fully reusable vehicle.
