I don't see this as a bad thing, maybe china landing people on the moon before us will light a fire on both sides of the aisle to stop fucking around with commercial space contracts.
Over-reliance on SpaceX is causing the same problems to Artemis that over-reliance on Boeing caused the SLS program. A year and a half behind schedule, blown their entire budget on a meme rocket that only potentially lifts half the tonnage promised.
The falcon rockets are fine but SpaceX has been raising prices on their launches since they won the majority of the contracts.
It used to cost 20 million a seat on the Soyuz until Russia became the sole provider of crewed launches, then they raised the price to about 80 million a seat.
Along comes musk and promises 20 million a seat and low and behold after the contracts are fulfilled they raise the price to 80 million as well.
SpaceX is falling into the same rut every company that becomes a monopoly enters into, and Starship is Musk's personal meme rocket the taxpayer has already shelled out 4 billion for, and there's not even a launch with a working payload.
SpaceX looks cool flashy as shit but they over-promise and under-deliver at the same rate Tesla does. Early success giving way to overconfidence and an inability to deliver on their lofty promises.
