We should go to the Moon because, if and when humanity expands into space, the Moon will be a major hub of transportation and industry for our Home World. Our Moon (the Moon) is ludicrously big relative to the Earth. There are hundreds of holes opening into massive ex-lava tubes running under the lunar surface. Earth’s 23.5° tilt means that every point on Earth will be exposed to the Sun at some point during the year. But just in case it is, there are more elegant ways to get to and from the lunar surface: by rail.
