I for one am glad that you were not allowed to short SpaceX. People gaming the market for their own profits are the worst kind of exploiters and swindlers. You contribute absolutely nothing while siphoning the profits that workers make, lowering the salaries of everyone that actually works for a living.

Note this has nothing to do with my feelings about SpaceX. I am Elon hater nr. 1 and hope SpaceX burns to dust, I only hope speculative investors burn down with it.

EDIT/CLARIFICATION: This post is fundamentally anti-capitalist. You may feel like I am mis-informed or misunderstanding. I am both of theses things if and only if Capitalism truly is self-evident.
