That would be "lock up publicly problematic addicts" not "addicts" in general. The aforementioned "functioning, respected and powerful people" are able to conceal or internalize the cost of their problems and aren't usually a problem for the public at large. With that in mind, the problem is really just being persistently a public danger/nuisance. The only relevance of addiction to this is that addicts are frequently unresponsive to incentives that would be sufficient for non-addicts.
