Trying to force multiplayer RPG's to work solo is a stretch, I give you that.

On the other hand, there are good, well made, solo-rpgs, aven though many are more of a creative-writing exercise than the monster-smashing/dungeon-delving/hex-exploring many of us associate with the genre.

Gentleman Bandit is great! Thousand year old vampire made me feel things!

The introverted guy you mention maybe could use some more people in his life, but that seems orthogonal to the existence of this interesting genre. Maybe if he didn't run his dungouns, he would be writing schlocky fantasy fanfic, or solving infinite number of sudoku. And while I might still slightly judge him as an introverted weirdo, I wouldn't judge him more, or less.
