If one pad is the bottleneck, and the goal is to ramp up to be a spacex competitor, then build more than one...
Falcon has shown the playbook, and the demand for launch... The goal should be 2-4 launch sites in the medium term; with a second site very early to avoid exactly this.
Until recently, SpaceX only acquired new pads because they needed a completely new launch site (SLC-4 in Vandenberg) or needed to launch a vehicle that their existing pad(s) didn't support (Falcon Heavy for LC-39A, Starship for Pad A in Boca Chica/Starbase). Currently, Blue Origin's only orbital launch vehicle is New Glenn, and their Vandenberg pad is still under construction.
Waiting until you need something and don’t have an easy replacement is how you end up with delays and bottlenecks.
Launch pads are not something you just buy on a whim to keep around just in case you need them. They're very expensive pieces of infrastructure that you only acquire when you have an actual, known need. That's how every launch provider that I know of behaves, including SpaceX.
I don't disagree at all, but I'm quite curious where the cost actually comes from. Even including all the harnessing and other hardware, it doesn't seem like something that should be a bank-breaker when we're casually talking about vehicles worth tens of millions of dollars blowing up, if not being discarded after a single launch.
I was going to say this too. And since we're at it: does anyone know how many launch pads the Chinese private space companies have, combined?
