You keep saying this, especially thing like: "reality of the SP will reveal the current valuations are unsustainable", and you mix together valuations and SP as if they are the same thing. The point that keeps getting questioned is why? IMO isn't an explanation, it's a identifier of where not why the statement originates. Are you claiming the SP won't likely reflect the value of the company for some time? Are you claiming that valuations of the company are too high? If they are too high are you talking about the ultimate value of the company at the point that it produces revenue, or are you talking about the risked current valuation of that ultimate value? This is why people make counter arguments such as that you seem to be implying that no current revenue justifies a SP of $0.
