Interesting. Two little issues: safety and ticket costs. Also, your average overweight tourist isn't going to be very happy at several G's.

Hey, I'm a bit overweight and I would be very much happy with the G's :).

That said, I think those are the two primary issues. Airplanes, cars and trains can break on you, but they generally won't explode.

So that's basically the first privately-owned ICBM?

Falcon 9 is already that, with the bonus that it's got a big enough payload that you don't need to miniaturize the bomb.

No, the current SpaceX rockets are ICBM enough. This is much harder - ICBM's don't need to land at ~0 m/s vertical speed, and if they carry nuclear warheads (are there conventional ICBMs at all?) they don't need ~1 m landing precision.

The security protections on the launch pads alone would have to be incredibly high. Looks vulnerable at sea like that.

My thought also, how will landing feel?

Your head would be happy but your heart might disagree. If a good chunk of the passengers gets moved to the ER, happy but with heart issues I think it won't be very popular.
