It’s not practical given our current technology, but theoretically it could be in the (far) future, in a situation where energy is abundant but matter is not.
Which, admittedly, is likely gonna stay a very niche situation. Mass is the densest form of energy that we know of, after all.
I also assume that if we get some exotic state of matter through this process and learn to extract energy at least 100x more effectively, this could become practucal for some applications
