True, but there will be a lot of competition for the number 2 slot. ULA, Rocketlab, Relativity Space, Blue Origin.

I would expect them to price Starship at or below Falcon 9 from very early on. That lets them move payloads from Falcon 9 to Starship. Every Starship launch is an opportunity to practice landing of the first and second stages. It makes sense to include commercial payloads for their practice launches even if they do so at a loss, because they need to launch anyway and some revenue is better than none.

They'll charge what the market will bear, and it won't bear more than Falcon 9 (for payloads Falcon 9 can carry) because Starship doesn't have the track record of success.

They aren't going to be launching with a reduced configuration unless reuse attempts go very wrong. They will launch relatively cheaply, because some revenue is better than none, but only with configurations that are potentially reusable so they can get reuse perfected.

If reusability didn't save them money I doubt they'd do it. And they've said it's much cheaper to refurbish than to build new. Those rounds were to raise funds for Starship and/or Starlink development. Both of those have been money-sinks.

I see the switch to methane as part of a sea change in the launch industry. Part of the realisation that hydrogen sucks as a first stage fuel, which is significant because NASA in particular were fixated on it for decades (and still are for SLS). Part of the New Space willingness to rethink old assumptions and ways of doing things. The switch is a symptom rather than a cause, but still a sign of the times.

By "large scale", I mean for example if P2P methane rockets replace much of the airline industry (as SpaceX hopes for Starship), and/or if methane replaces fossil fuels in other industries. Methane itself can be carbon neutral, so leakage may be its biggest drawback.

Given how popular methane rockets are nowadays, it feels strange to me that none have yet made it to orbit. Hopefully by the end of the year two will have.

If it is ever used at large scale, methane leaks during production and transport could be an issue.

Nothing. I enjoyed movies with surprises the first time around, like Fight Club or The Prestige, but I also enjoy them knowing what's coming. Some films can't be fully appreciated on one viewing.
