Even the SLS cost less than $50bn to develop, which is a lot, but only a fraction of what SpaceX is apparently worth.
Developing a new rocket like the Falcon 9, even a reusable one, would cost a private investor less than $10bn. It would take time, that is the hardest part. But in terms of cash, it is a fraction of this valuation.
Then a constellation like Starlink - again, we are talking $10-$15bn. Once you have the rocket, the satellite design is not going to cost much. The challenge is getting the regulatory approvals and getting the launch rate up.
Then developing something like Starship, again a few billions, certainly far less than $50 bn. A crew capsule too, that would be a few billion, but probable <$5 bn.
For a trillion dollars you could probably throw in a space station (the ISS was about $100bn), a few advanced orbiting telescopes, a human mission to Mars, and maybe an intensive exploration of Europa. Heck, why not land something on Pluto just for kicks.
