I'd argue that excessive play causes a very serious "detrimental problem" to those who are not employed, aren't in relationships, and don't have children. Someone in that situation is already facing a serious disconnect from society, and excessive play presents a major barrier to resolving that. This might be a secondary issue in the way of some underlying problem, or it could be the main problem itself. It's a problem either way, and one that has to take priority.
