Something to think about: pretty soon there will be nothing strange about a rocket that has flown before. Contrast it with the feeling you have for a 737 that has done 2500 starts and landing prior to you going on board, it's a sign of confidence that it did that. Now it will be many many years before there will be boosters with numbers of take-offs and landings > 20 or so but at some point insurance premiums for unflown hardware will be higher than for hardware that has been flown before.
Huge game changer this, also in the frequency of launches.
