Having freedom and drive to do whatever you want is great, even if that means you spend a bunch of time just fucking about and getting high and watching TV.
On the other hand, a lot of the people that are dropping out like this are actually just depressed. They look like they're doing the same thing, but they're actually just self medicating and it sucks for them.
For some of these people, getting up and out the house, being forced to do a bit of exercise, and talk to people can help with minor depression.
