There can be no socialism without a state, and as long as there is a state there is socialism.

“There can be no socialism without a state, and as long as there is a state there is socialism. The state, then, is the very institution that puts socialism into action; and as socialism rests on aggressive violence directed against innocent victims, aggressive violence is the nature of any state.”
― Hans-Hermann Hoppe, A Theory of Socialism and Capitalism: Economics, Politics, and Ethics
