Dependence and Independence.

I believe that there are many facets are dependence, and a person who thinks that they're ready to live on their own really might not be ready in all respects. For instance, a person who has a job and is able to pay the bills be still relies heavily on their family support system might not be ready to be own their own emotionally.

However, no one's ever completely ready to be independent before they leave the nest. Any one who's moved out to live on their own can attest to how much they had to learn and cope during their experiences. So at some point, I think that most who are still attached to the environment they grew up in should be pushed out on their own -- much like birds are pushed out of their nests and forced to fly.

Then again, everyone has their different situations, so it's inappropriate to judge another. Still, I'd like to think that this at a certain age, unless under dire circumstances, one should be (at the very least) making strides to live on their own.

Jam it back in, in the dark.
