Is it likely that SpaceX will have actual reasonable demand? Their major customer is Starlink. How legitimately confident are we in the numbers with regard to price reduction vs creative accounting to offload costs to Starlink and subsidize the launches to appear to offer huge cost reductions?

If there exists sufficient demand for the product of space launches then it's probably reasonable to expect their to be a near-peer competitor soon, but that's only if SpaceX were to be profitable, which it isn't, even with the subsidization by Starlink on the order of many billions.

There is about 3 chinese orbitallaunchers with some reusability support flying & about as much scheduled to debut this year.

But other than that, yeah - outside of China, progress has been horrendously slow & Blue Origin, the only other US company that demonstrated a partially reusable rocket just had a devastating pad explosion, destroying one of their 2 rockets and their only launchpad.

Doesn't SpaceX charge 2 to 3 times their internal cost to external customers? ISRO is still more expensive, IIRC they charged ~US$60 million (roughly $6000/kg) for the OneWeb launches whereas after the recent price hikes SpaceX is supposedly charging ~US$74 million on a larger rocket (~$4200/kg), but that's far from an order of magnitude difference like your comment suggests, which I assume would be using the $25 million they charge Starlink internally (IIRC ISRO's internal cost is much higher, around $40 to 50 million, but that's still not anywhere near an order of magnitude). Using internal cost from one provider and external price for another is somewhat misleading.

> future projection and goal is $100 per kilogram

This can't be treated as meaningful, given other projections and goals (Mars colony, etc.).

how many packages have you shipped so far to space? SpaceX could disappear tomorrow and most people wouldn't notice. Your satellite TV might get slightly more expensive. Those rare people that don't have LTE internet access and need starlink are exception.

At the rates you quote, $1 T (the size of the market) is 714,285 tons of stuff in the space each year. I don’t think there is enough space in space for that much cargo.
