SpaceX could voluntarily split into two arms-length competing companies, neither of which are as competitive as SpaceX today (because each only has half the resources), but both are more competitive than ULA.
Doing so would reveal that Boeing is supported not only because it's worth having at least 2 launch providers, but because politicians friends have investments there...
That would be interesting and maybe not even unprecedented after the Texas vs Florida build off with starship. It might be hard to replicate the leadership team though.
