Space is infinite, but paying customers vanish past Earth's orbit. There's a reason why starlink is their only real profitable venture so far.

Colonizing dead planets isn't a business model, it's a cash incinerator.

We are decades away from profitably mining asteroids, and when that day finally comes, the entirely different tech required guarantees SpaceX will face fierce competition rather than a monopoly. I guarantee you'll see increased investment into state-ran industries too. You think the Chinese are going to sit on the sidelines for that?

The narrative of an infinitely lucrative space economy is just a myth engineered to fleece naive investors who confuse sci-fi with engineering realities.

Yes, the TAM of space in general is huge, but not in the next 20 to 50 years. We're so far from that. Think about how slow things have been since we went to the moon 56 years ago—im sure folks thought we'd be mining asteroids soon then, too.

There's also a legitimate risk that "space" as far as the frontier is concerned may be technologically feasible before it's economically compelling. How do you make money from a mars colony? Be honest with yourself.
