He's actually on the pathway to schizophrenia and needs close friends to keep him grounded but he's pushed all those people away so all he has left are yes-men, clout-chasers, and whores who will only enable him further...
Erudite would be one of destiny's close friends but she's just some canadian expat using him as a meal ticket, incapable of criticizing him in any meaningful way so as to not risk everything she's ""worked so hard"" to obtain so far; so she ends up just further enabling his antics and similarly spergs on twitter because becoming a budget-destiny is the only way to ensure she doesn't get the boot
The username 'notsoerudite' is just a politically-correct way to say 'retard' and it's very fitting
Similarly during the divorce, erudite was very careful to never blame steven for anything directly, it's always some tangential thing he is already aware of that gets blamed; with the divorce it was his "boundaries" and now it's his "tone" two shortcomings even destiny isn't delusional enough to realize he has; so rather than fix any behavior destiny gets to just be like, "ok duderino, gotcha anything else?" and change nothing because things are never his fault & he's always right, then he goes forward repeating the same mistakes, burning every bridge, etc etc
Other than that who does he have? Dan he treats like shit, somehow Dan is resilient enough to wave most of it off. I think Destiny is doing a disservice to Dan though because i think Dan only hopped on ADHD meds and Benzo pills to sleep after seeing how much it increased destiny's productivity.
And MrMouton, destiny's former viewer groomed into best friend; Destiny had to be dragged kicking and screaming to attend MrMouton's wedding, and was only able to make it after finding a last minute fuckbuddy + he didn't even stay for the entire thing
