Benzos work on GABA receptors. That does suggest some interesting possibilities for those whose addiction is thought to work via GABA receptors, but that wouldn't cause interaction with naltrexone. They're two different drugs.
I suppose they might hamper psychological progress in that we're still turning to drugs to deal with our lives. Some of us swap one addiction for another. One can get "relaxed and mellow" from either drug, even though their actions are different.
