The moon landings were pretty awesome in their own way, but at the end of the day, with the way they were done, it was basically a stunt. None of it put any infrastructure for the long-term access of space into place, or anything to make future moon landings easier.
This paves the way for the costs of space flight to be cut in half, or even a little further. This has the potential to set off an exponential chain of growth of space travel. The further they cut prices, the more customers and launches there are. The more customers there are, the more profit they make, to be plowed back into better, more reliable, and more reusable rockets. And the more incentive their competitors have to come up with their own reusable rockets. The more reusable they are, the further they can bring prices down. Every step reinforces the next, and in 30-50 years, the price of a launch may well be a tenth of what it is today. Maybe closer to a hundredth.
What will we build when access to space costs 1% of what it does today? Maybe a huge space station, or a moon colony, or asteroid mining, or all of the above. The more traffic we have to space, the more infrastructure we build, and the cheaper and more reliable it all gets. Off-world colonies might become about as practical as a trip to and colony in Antarctica is today - still tough and hazardous, but well within the budget and vision of any developed nation. This is freakin' awesome for the future!
