> Seeing the progress of spacex's VTOL rockets has made me wonder what's stopping us from using rockets to move things and people (if they don't mind the g-forces) around the planet.
People, and very many things, definitely "mind the g-forces".
> I believe I read somewhere recently that you can move an ICBM between any two points on the planet in less than an hour.
You cannot.
You can use an ICBM to deliver a payload between any two points on the planet in that time, which is considerably different than moving the ICBM.
> Seems like there are things - and people - we'd pay a big premium to move around the planet that quickly.
Part of the "that quickly" is that, well, impacting at multiple km/s. There's not a lot of things or people that would survive being delivered in that manner.
> Is there some fundamental reason that makes this not work?
As covered elsewhere in the thread: cost (ICBMs aren't cheap), fragility of most of the things you'd want to deliver (and most of the places to which you might want to deliver them), and the fact launching ICBMs is a good way to start a war?
