The solar system readily provides both the motivation, and the means, for technological colonization. It quickly pays and provides for its own utilization.

I do agree Musk's projections for biological/human colonization appear to be unrealistic. Just one challenge: it isn't clear humans can reproduce in non-Earth gravity. That is an extreme impediment.

Celestial mechanics suggests it can hardly be economical to move large amounts of matter around a solar system for economic goals considered in the current capitalist societies. Nor the risk, nor the energy needed are in line with the benefits.
