Chipping in here. There's a lot of speculation on this subject matter, all of which entirely wrong.

Technical concerns aside, the main risk is financial. Success is based on the premise that we need this enough that the costs are justified but the costs are going to be much higher. That is totally unproven on any financial modelling scenario I've seen. In fact there's likely no actual ROI on what has been spent so far and no qualification of demand. With geopolitical problems on the table, no one is going to fund this.

The idea is completely dead before the first node leaves the planet.

Not only that! First mover advantage is mostly bunk. Even if none of what you say was true, valuing this on a horizon far enough out to solve all the technical problems gives a lot of space for competitors to emerge. So even if the idea was both technically and financially workable, there is no guarantee that an investment in SpaceX specifically would be the right move over the same evaluation term as the tech will take to play out. It only makes sense from a speculative angle because you know that if they present any more concrete excuse to believe that the tech works, the price will temporarily go through the roof.
