Probably one of the best things NASA could do at this point is abandon ISS, stop paying for it, and tell the Russians its all theirs. There is a fair chance they would fly Americans to it for free rather than get saddled with that boat anchor.
If the Russians don't want it either its time to deorbit it. It would free up a LOT of money for more useful endeavors. Its never been good for much of anything, certainly nothing to justify the staggering price tag
SpaceX will have the ability to put astronauts in to LEO in a few years. Its not like its a crisis, there is very little for people to do in LEO at the moment other than to be lab rats for zero G physiology studies. You would think they would have done most of that work by now.
About the only point in putting people in space at all is as colonists, persumably on Mars. You can do just about everything else way better and cheaper with robots.
So until you are ready to fly people to Mars to stay, stop getting your panties in a bunch about getting them to LEO.
