Yes, also there's a world of difference between a single extremely hard to repeat mission whose only purpose was to win the race to the Moon at any cost for reasons that had more to do with politics than engineering (not to dismiss the huge engineering accomplishments, my point should be clear) and something whose plan is to send stuff in orbit every week and potentially people every month with the goal to do the same on the Moon very soon and Mars in less than a couple decades.
The great accomplishment today isn't reaching a higher orbit than in the 60s, but doing the same every damn month, with significant cargo capabilities, and safely. One can't build a Moon base by sending up there a bag of screws every six months.
What do you mean a "single mission", Apollo put astronauts on the moon 6 times and orbited it another 2 times.
You learn to do things better by doing it repeatedly. The best way to build up to weekly launches is to do it more and more and more often, which is exactly what SpaceX has done.
Stopping the funding that NASA was getting at the time is the reason we lost those institutional muscles and stopped building them up.

Possible bad wording on my part. I meant that the cost was hardly sustainable in a long run, so that once it was clear that the US had won the race to the Moon, the lack of significant incentives doomed the project because of high cost compared to the return. Back then there was no or very little interest in placing commercial satellites in orbit and nobody cared about Mars. The shuttle was different as it served as a lab and carrier to put satellites in orbit, and more importantly (replying also to avar here) disasters aside one would still have the shuttle returning after each launch, while every single Saturn V had to be rebuilt. I believe the move to a reusable carrier was obligatory to make short term launches feasible economically, which is what the Shuttle started and now SpaceX is continuing.
I don't buy that the cost was unsustainable. All that money being spent was going directly into the American economy and was stimulating technological development all over the country.
The story that NASA was too expensive during Apollo sounds like political spin to me.
Apollo's single mission was "get to the moon", which it performed admirably more than once. Skylab was an attempt at a secondary mission; others were canceled in early planning (https://en.wikipedia.org/wiki/Saturn_V#Post-Apollo_proposal).
