Sure, I'm comfortable with that.
However it's a disingenuous to claim that Marxist political philosophy doesn't imply extreme centralization in practice. You're substituting the Marxist political projects of today (and yesteryear) with a hypothetical as-of-yet-unobtainable Marxism of the future.
I'd be a Marxist if all its problems suddenly disappeared and we were left only with the upsides. Who wouldn't?
