It's sobering to think, nothing the entire private space industry put together has proposed comes close to what NASA was sitting on in the 1960's, with nuclear pulse propulsion. Now it's unthinkable. But with a slightly different historical path, we could today be launching thousands of tons at a time into orbit, on a trail of small atomic bombs.

Exactly. I buy that we need a space program, but as far as I am concerned a government space program has had its chance.
This is not the end of space exploration; on the contrary - things are going to start advancing at a much faster pace.
