What do you mean "let it fail?" SpaceX has the most profitable launch system in the world and now operates >50% of all satellites in orbit. They aren't exactly in need of a bailout.

> Bring back NASA.

NASA is still here. Unfortunately, NATA fell victim to enshitification by government contracting. NASA even if it wants to simply cannot today design and launch a rocket. :(

I am no fan of Musk the man. SpaceX is a strong company and Falcon is a solid vehicle. There is not a lot of competition, and NASA trying to in-source design and supply and construction of a new, reusable LEO rocket would be a complete nightmare.

I root for a competitive rocket market, but SpaceX is at the moment critical.

You want to bring back the biggest loser? NASA kept missing deadlines for 30 years

NASA just splurges money. The private sector is far better when it comes to money.
