IMO there's a world of difference between writing that's not particularly accessible and intentional obscurantism or esotericism. You're obviously not the latter, and I think what I'd recommend for you is to break up the more dense stuff with sort of a Chit-Chat style. So for every sentence with heavy terminology, have a sentence where you crack a joke or poke fun at the other guy's argument or restate the last sentence in a funny way or try to think of an interesting metaphor for your argument so that the neophytes can follow you. I'm not saying you should dumb anything down - far from it - but I think the main problem, if you want to call it that, is the density of the language, not necessarily being obscure.
You have no idea how it bugs me when I realize I'm obscure in writing :/ It's all bullshit, I want to get rid of that kind of writing habits.
I just realized I completely misunderstood this sentence: "The issue with not engaging in the relationship of capital and wage labor is, in my opinion, crucial in thinking about that class since this relationship which is manifest in a very concrete way is crucial to the development of class struggle (these are its basic actors)." And I completely agree with that now. My bad.
