My first comment is that while I do think the issue is real, and that's why I talk about it, I aslo think that the most pressing part of it is not those who actually do retreat from society, but those who think that it is great intellectual fun to sarcastically or caustically observe that Epicurean philosophy is just as full of wholes as any other because it seems to preach pleasure but at the same time preach asceticism.
In other words I think there are many who like to talk about Epicurean ideas of tranquility but few who actually try to live it (for the same reason they don't love Stoicism).
They are fixating on impractical and "wrong" ideas as what Epicurus taught, and then that gives them license to keep him on a bookshelf with 100 other gurus who they pull out when they want an intellectual challenge but otherwise ignore.
Having said that, yes the questions Kalosyni raises are good ones. In many of those cases a person considering those alternatives would really be in a downward spiral even to be considering them. Such situations don't call for retreat to "mind over body" as much as they probably call for focused action to attack the problems causing the issues.
