I would rather have successful AGI before universal replicators that are available to many merely human intelligences. Super especially hope for that if these replicators operate at the nano scale, which I think you're implying with the suggestion everything can be made from common raw material like dirt. But I'm not too optimistic. Governments couldn't even stop proliferation of 3D printed guns, how will they cope with other things in the future that have an economic incentive too? Don't forget that even if certain materials no longer become rare or contested, location and raw energy will still be. Without a supreme AGI, or an upheaval of our most basic knowledge of physics, expect wars to be fought over rotating black hole real estate.
