Your sentence was the direct response to the question:
> Yeah, but is SpaceX actually worth $1T
The question and context of your response was about SpaceX's present value. Given the context, I think my response was absolutely a fair reading of your response.
Markets are forward looking, pricing in future cash flows. No one should be thinking about SpaceX's present value when buying their stock. If you do that you'll always be too late to the party.
That said, I don't agree on the valuation, but I can see where some people could be coming from.
