Yeah, I agree with the idea that planetary colonization is not the best idea.

I'm more of a massive spinning space station made from asteroid/lunar mined materials kind of guy myself.

But if harebrained ideas to colonize a body with substantially lower gravity that may no idea if the human body is even compatible with that lower gravity get us the infrastructure needed to get lots of stuff into space then so be it.

I think anyone expecting space to yield exploitable resources at a feasible cost isn't really thinking this through and/or isn't being real about how big and empty it is.

Can you elaborate?

There is no substance that can be practically transported to earth from space at a cost that would justify the transport costs.

Are you talking about the current transport costs or theoretical optimal transport costs?

What do you think is the biggest part of the transport costs and why in your opinion can it not be reduced?

It's dumb because it's not practical yet?

Because it has no conceivable benefits and staggeringly huge risks and costs
