You're partly right: the deuterium-helium-3 fusion reaction has the advantage that no neutrons are produced. This reaction, however, requires higher temperatures than deuterium-tritium fusion, and is more technologically challenging than deuterium-tritium fusion.
Having said that, I work on a fusion experiment. Its configuration is such the deuterium-helium-3 reaction may be required to make a workable reactor, and the notion of mining He-3 from the moon has been a subject of serious discussion
