Okay, Mr.Big Shot. You got it all figured out, it's only the losers that will wander aimlessly.

People have interests outside of work, those will fill in the role of work and new ones will be created. No functioning person wants to stand inside staring at a wall, they want to do stuff. They will find stuff to do.

To reiterate once again, both points you brought up can be fixed by just spending time on your hobbies instead of work. New friends will be made just in the same was as work. It can come from a chess club, gym, painting class.

You're just rambling.
