That’s the socialist definition of class, that is not how I understand class.

I can decide to understand gravity as a color if I want to, but it doesn't make me right.

Calling bureaucracy “nebulous” doesn’t invalidate any of the reasoning I provided

I'm calling the term you're using (beauraucrats) nebulous, because it is, because you haven't defined it. You haven't provided any "reasoning", you've just said "I think this happens" with nothing at all to back it up.

Suggested approach: anarchism.

That's cool, but some of us feel like living in a society that doesn't get rolled over by a capitalist military whenever they feel like it. Some of us enjoy functional supply chains, too.

I didn’t disregard the importance of understanding class, merely that I disagreed with the reductive socialist definition of class.

Yeah I'm not saying you don't think it's important, I'm saying you don't understand it. Please tell me what you think is reductive about the definition of class used by the people who have radically transformed multiple feudal societies into world powers, because your own track record does not make a compelling case for abandoning it.
