I'm pretty sure that would lead to a near absolute zero survivability for anyone on board a system like that.

Yea, but a catapult or railgun would be fine for water, certain foods and other durable goods. Then the crew could take a smaller, cheaper rocket up.

That's true. I wonder what the energy use would be in comparison to chemical rockets. And if it would be inherently safer since it wouldn't be moving via a controlled explosion.
