Re: It's about government control
The price of SpaceX rockets is far below previous generations: everything is cheaper, and they seem to be quite reliable.
As for SLS vs Falcon Heavy.. how can you claim the SLS is more reliable when it hasnt been used? I would say it is unknown.. designed to be safe for passangers (or as safe as these things are), yet untested.
If I had to sit on top of one of them, once the falcon heavy has been tested a few times, I would go on a falcon Heavy.
Going back to price.. it is not that SpaceX is a bit cheaper. It is several times as cheap.
