Many companies can afford and buy expensive launches (Adriane etc) so they prefer SpaceX to save money

Many other companies can't afford Arianne launches but they would afford Falcon 9 launches. Lower prices generate a bigger consumer market

SpaceX wants to put thousands of their own Starlink satellites in orbit

So what prevents SpaceX from maiking a launch every one or two weeks? Or one each three weeks.

One source says payload fairings are slow to make. Yet they can hire more people so where are the major bottlenecks that slow the launches?
