Yes, and for bulk cargo it seems to me that it would make absolutely no difference whether you have a base like this or a lot of shuttles. But for passengers, you could have a large, luxurious, very massive base that you put into this kind of orbit once and a lot of small Earth and Moon - based shuttles that transfer passengers to it and from it. This way, passengers sit inside small, cramped, low mass shuttles just for the start and end of the trip, instead of them being cooped up for the entire trip OR you having to waste fuel to accelerate and decelerate a much larger, more comfortable shuttle for every trip. I mean, it\'s bearable to fly third class for 2-6 hours with a fat guy jammed next to you, but 2-3 days or more? For any journey longer than 24 hrs you are going to need a lot of extra equipment (food preparation facilities, lavatories and waste management equipment, bunk beds/seats, artificial gravity centrifuges or cryogenic pods or whatever, and it is a lot more efficient to accelerate all that extra mass ONCE and keep it a station in this kind of orbit than to keep accelerating it along with the shuttles... As someone said, this would probably be more useful for Earth-Mars than for Earth-Moon because of the longer trip times...
