I think we're just nitpicking over "need" and "makes sense." The need is connected to Mars colonization which is now on Starship's shoulders. I also think that Elon has realized that numbers are more important than speed. You definitely don't need a quick turnaround time when your vehicle is going to be taking many months, to over a year, to get to and from Mars. Certain aspects of Starship will need a quick turnaround time because of orbital refueling. Not that taking a week to refuel is that big a deal when your journey to Mars is four to six months.
Falcon 9 is limited by pad availability and booster recovery times. SpaceX does have a new West Coast pad coming on line soon to really max out the launch cadence. They will need another West Coast ASDS if they are going to launch from that one regularly. Pad SLC-40 has done the bulk of the launches this year. I wouldn't be surprised if SpaceX doesn't buy another pad in Florida this upcoming year. Then SpaceX can go for 150 launches for 2025.
