In short, the social harm done to [by?] expansive, unaccountable government is WORSE than the state interference and ownership of state means of production, as bad as that is.
Agreed. But expansive, unaccountable government isn't socialism. You might argue, and I'd agree, that socialism tends to produce expansive, unaccountable government. But so can any social theory that advocates for more state power (eg nationalism).
We just need to be more accurate with our terms if we're to have any hope of making intelligent decisions as a society.
