Just because you are better at some things than someone else doesn't stop you being jealous and resentful of them, if that's the sort of person you are.

Self hate has a lot to do with it, and Dylan had a lot of that, you can see it in song after song. It's a sort of fuel.

It's a bit interesting speculating about what was in someone's mind when they write a song, but it's not the end of the story. All kind of things can set off a song, and the song is there at the end of it, and if it's the kind of song Dylan was writing then, it can apply to all sorts of other things. A branch on a tree might grow in a particular shape because of the wind and the weather, but the important thing, if someone's turning it into a didgeridoo, say, is what shape it is, rather than why it became that shape. (Not that I've ever made a didgeridoo, but you get the point.)

Positivily Fourth Street isn't "about Phil Ochs". It's about broken friendship and stuff like that. And that's why it's a good song, because we all experience that sometimes, at a personal level, at a group level, at any level you like. You could quote it in any of the threads about national flaws we keep getting in the Mudcat, and it'd be relevant to that. Or men and women. Or flaming.
