It is completely clear where the 60k number is coming from. Whether you agree with it or not (he did qualify it as speculative) if you don't know where it came from then you must have replied to his post without actually reading it.

You are right, maybe I should have said where the sub-100$/kg comes from.

In the first Starlink launch, with 60 satellites of ~230 kg each, the cost of launch was ~$30M (considering that the "retail price" of a Falcon 9 launch is $60M, I guess that half the cost if a good assumption). Thus, the cost per kg was $30M / (60 * 230 kg) ~ $2,000/kg. I just don't see how they are going to achieve a x10 reduction in cost, even considering reusability, larger masses, etc, etc.

Yeah, I guess we'll see. Economies of scale and complete many-times reusability of both stages sound like plausible multipliers to me, but it's all speculation until the thing flies a few times and they get a mature production line up and running.
