Yeah, true. But come to think of it, loneliness does more good than harm. On your road to success, you've got to be alone; no friends or family.
Most great ideas come to us while meditating, and we don't meditate in a social state, it all goes down in a state of loneliness.
We set goals, plan and strategize when we are alone. Those who are in constant need of companionship are... well, I don't know what to say, but you must be truly lonely to make relevant contributions or add value to the lot.
