This person seems to have a really cynical take on management. The best answer I have to it is that management becomes a fundamental necessity to have productive teams and that applies regardless of remote work vs not.
As soon as work scales beyond what a single human can do in complexity and / or size you need multiple humans. Proceeding forward without anybody actually coordinating what those humans are doing turns out to be a disaster for multiple reasons, many of which if this person was subjected to the situation, they would immediately invent an equivalent of a "middle manager" or boss to solve.
I actually don't see the need for this decreasing with remote work, in fact I think it might increase.
