> Think on the order of "One succesful launch, delivery, and re-entry/recovery per day".

Given that they have largely relied on reusability rather than strongly ramping up production of boosters for Falcon 9, and given that they have performed 3 launches in a single day, one launch per day is clearly achievable without any further advances, and without even using Starship.

To be clear, the stated goal for Starship is one launch per hour throughout the year, which would still be a tiny number compared to, say, airline flights, but quite impressive for orbital flight.
