This. That last one definitely. They would be more about the downfall of American space flight rather than trying to do ridiculous things with it

Don't worry anon, NASA will get us back to the moon soon!*

If Starship makes space access as cheap as SpaceX aims for, then what kind of sports would be popular in space?

What kind of space sports would appear in the Olympics?

>A train would literally be faster than a descent and cost zero propellant.
If you are commuting 10km away from where you started maybe.
If you want to go on the other side of the planet a rocket is faster.

>Trains are very comfortable. Way more comfortable than any spacecraft to ever exist and always will be, nor do they need to be for “tourism”. Ever heard of a job?
For a Space-Surface transfer you won't need to stay more than a half-hour in a rocket. Train will takes hours even if you built magnetic rail everywhere.
If we are talking of real travel you could travel on spaceship more luxurious than a train will ever be.
Also check out the concept behind Aldrin's Cycler
In space you can move anything that support the acceleration. On the ground you'll be limited by size and plenty of practical limitation you don't have with self-contained transport system.
It's as if you were trying to argue for living on boat or train instead of having cars or planes.

>Trains don’t need fuel. They need energy, which can be provided by local solar power, nuclear, or whatever.
They need a gigantic infrastructure, constantly maintained even when not in use and forcing it to allow human tourism will ruin your efficiency.
You'll need to build space infrastructure and exploit space resources first to make anything out of a planet like Mars because it doesn't allow easier access to everything you need.
So in practice you'd use less propellant living in space.

>50,000 years away
That's shorter than it would take you to bring interesting features down your gravity hole.
We'll live in O'neill space colonies faster than trying to make anything worthwhile of an irradiated cold hell like Mars.
