They are spooling up commercial passenger rocket flights (for cross-continent travel) in 5 years and won't likely have renewable sources by then, they have already put in or filed to put it pipelines for petro industry gas sources in Texas.
"Spooling up"? It's currently an un-launched prototype that isn't yet human-rated let alone passenger rated.
Why do you think they can move faster on that than on tech invented prior to the birth of the oldest currently living human?
They gave the timeline for entering passenger service competing with long haul aviation back in 2018, sayijg within a decade. Years later they reconfirmed that timeline.
You're willing to buy his estimate for a timeline about a thing you don't like (I've seen him talk, even he knows his timelines are optimistic, and he shows much the same optimism about FSD) while totally ignoring the thing invented before any living human was born and which is already deployed in various places?
Why?
Fortunately some French scientists figured that out how to do that 126 years ago.
