Dictatorship of the proletariat is supposed to be in theory a transition period. In practice, once you get the power, you keep it.

Other on the far left will rather go a more local route, destroying state structure (as state is oppressive by nature) in the beginning to create a collective bottom up.

I'm not saying any of this is a good idea btw, it's just that far-left has fled the US a long time ago. If you aren't revolutionary, you aren't far-left.
