That’s not a bad idea actually. Put humans in a pure-oxygen fluid container, like Ed Harris’ character in The Abyss, because I don’t know what kind of pain someone like you would be in due to leaving gravity with that much G-force.
I could deal with the pain of launch. I’ve got junk knees, ankles and hips but would be mostly OK in lower gravity like on the moon.
Now that I think about it, low gravity environments would be a great place for intensive physical therapy.
