One consequence of SpaceX being private is that the share price is likely much lower than if it were publicly traded. Whereas the Tesla stock price tends to be volatile, the SpaceX price seems likely to remain relatively stable and continue to increase in a monotonic manner. In the event of a prolonged recession, I feel that SpaceX shares will hold their value, but the Tesla share price could drop substantially, at least for a while.
On the other hand, what difference does it make if the SpaceX share price remains stable if it's nearly impossible to liquidate? Or would it be nearly impossible? I suspect that if anyone on this thread were to express interest in liquidating their interest in SpaceX, they wouldn't have difficulty finding buyers. Any ensuing transaction would have to be approved by the management of the relevant SPV (Special Purpose Vehicle), but hopefully that wouldn't be too big an issue.
Going a step further, perhaps residences could be constructed atop centrifuges. This would be expensive, but I think the vast majority of colonists, particularly early colonists, would consider it essential to give their offspring the ability to spend time on Earth. For that matter, preserving bone health and muscle tone would be of importance to the initial colonists as well.

I've also considered that problem. Perhaps it could be mitigated by regularly exposing all colonists to artificial gravity equivalent to 1g. That could be accomplished using very large centrifuges on or below the lunar and Martian surfaces. The "floor" of each centrifuge, where people would spend time, would be tilted at an appropriate angle relative to the planetary surface.I wonder if people have really thought through what is means to be a lunar or Martian colonist. It means raising kids there. And those kids probably wouldn’t develop the bone structure to exist on Earth. It’s a one way ticket for future generations.
