Ah, so this is what you mean by that. Still, bad focus. Ever since Hoxha’s Albania, Socialists have been pursuing the separation of the government and the economy as separate governing entities. So any claim that Socialists advocate for a strong central government is outdated at best. In reality it was always an askew argument as the people have far more democratic control over their lives than under capitalism.

“Market” Socialism is not necessary. Socialism pursues a dictatorship of the proletariat, not the total eradication of the bourgeoise. This means that socialism has to have some form of private ownership and thus some form of market.

Authoritarian does not mean anything. Dictatorship is the democratic domination of one group over all others. A dictatorship of the proletariat is inherently more democratic and less corrupt than a dictatorship of the bourgeoise.
