Yeah, I think that was the intended reading of that reply given the obviously similar phrasing.
However there's a word for anti-authoritarian leftists. We're called anarchists. Not all leftists are anarchists and not all leftists are anti-authoritarian. Even authoritarian leftists (or "statists") generally believe in the end goal being the ideal of a stateless, classless society.
Statists just tend to believe the only way to get there is with an intermediary socialist state established through a communist revolution and led by a vanguard party who directs the economic, social and philosophical evolution of the people towards bringing about communism. The differences between those groups are largely about what that intermediary state should look like and at what point it can be dissolved.
Some of the aspirationally communist states of the 20th century justified their continued existence with communism having to be rolled out globally simultaneously for it to b successful. Some instead argued that what they had achieved was "real socialism", heavily implying that's as good as it gets and any critics were utopian idealists who'd rather tear down the local optimum in the hope of an unachievable ideal. The USSR opened its markets and collapsed under the dual load of its bureaucrat aristocracy and capitalist oligarchs, China pivoted to Dengism to contain their "capitalist experiments" with the promise of a greater good coming from the temporary toleration of exploitation.
But for anarchists (and mutualists, who fall somewhere between anarchism and statism) the biggest problem tends to be that they usually either start out or end up surrounded by nation states with standing armies who want none of their nonsense.
The most promising approach seems to be dual power, i.e. building anarchist structures[0] within existing states through cooperation and solidarity so that when they inevitably collapse in the future, the people can fall back on those structures as an alternative to just reasserting the old (hierarchical) power structures.
[0]: To preempt the obvious joke: contrary to the portrayal of "anarchy" in most media today, anarchists don't believe in no organizations, just no hierarchical power structures, i.e. usually they agree with consent-driven forms of bottom-up organizing. The one exception tend to be egoists (see Stirner), but most anarchists try to ignore them because they're weird.
