To get people to question why.
To say another bead of your own string or another string has never been alone is presumptuous. After all, you observed we each have our own individual reality and thus experiences. To say whether being alone is a good or bad experience is only relative to each bead.
Say a bead is in their early 20s, for whatever reason emerges from a correctional facility in a major city they don't know well with no money, no one to call on, no way home other than to walk halfway across that city whilst examining their former philosophy of not giving a damn whether they live or die, they too can have a eureka moment in aloneness and decide it's actually nice to be alive and free and to get their act together and live up to their potential. In my experience, the romance of solitude achieves a similar effect if you're open to it and is the easier route to go, but I could be wrong.
So I am of the opposite opinion that events can occur in the reverse order. You can find yourself truly alone, and then get over yourself. From then on, aloneness is a state of mind, and uniqueness has nothing to do with it.
