Just like on the Earth, needed stuff may not be in a convenient location. As on Earth, one way to improve the situation is to have a device that will move the stuff around. Like a railroad, for instance.
It so happens that a lot of iron exists on the moon. It is combined with oxygen, so in the process of mining for oxygen, one can also extract iron. One can make some iron rails and connect them together into a railroad line. One line could reach from the pole regions, where water is believed to exist, down to the equatorial regions. Or to regions where significant deposits of useful minerals, such as thorium, are located.
Could railroads be built using robots and teleoperation methods? If so, a transportation could be put into place before significant numbers of people land on the moon in order to work there.
