I know it would be beneficial, but weight rooms are populated by people I dislike interacting with and do not wish to be like so that just sticking around takes extra effort. And AFAIK none of the programs like starting strength are the kind of thing you can do in your apartment with minimal equipment (if there is one, I can probably manage that).
Although I am likely biased by the location of the gym I go to, the real unpleasant experience for me was admitting that many of the "enemies" are in fact very reasonable and intelligent people.
