Which mirrors what I remember from said ESA study (which for love of the universe cannot find online anymore, and I didn't download it back the day). The big question I took from that study was, which was also the point of it, was whether or not if there is enough demand to get over that threshold (whatever the ESA number was) to justify the development of a reusable booster. The answer back then was, back when Starlink wasn't a thing yet and the Russians were still in the market, was no, there isn't enough demand.

Today, it seems, a lot of the launch volume comes from Starlink, which is basically SpaceX in-house demand for something we have no clue about its financial viability or profitability. Hence, I am quite sceptic about a lot of the space launch stuff. We have quite reliable numbers for SpaceX competitors (launch costs, development...) while SpaceX is somewhat of a black box. That alone makes comparing claims from SpaceX (which might well be true, but we cannot tell either way) to verifiable numbers from others dubious at best.
