Humans inevitably organize themselves into heirarchies. Generational heirarchies with monopolies on violence that reign with implicit assumed authority and inadequate checks from those governed by them take on a nature that begets philosophical, intellectual, social, and political phenomena such as 'anarcho-capitalism' and 'libertarianism.' These are cultural and/or heirarchical organizations of people with aims to bring about regulation of other heirarchical organizations of people that have outgrown their practical or ethical bounds.

Where no state exists, humans organize themselves into heirarchies, which themselves can be called 'states,' if you like, but remember the first goal is to have your own mind wrapped around ideas with clarity, and the second goal is to communicate those ideas with clarity, or perhaps to implement them silently. Ignore language / semantics that are not helpful to those ends. Keep in mind that government can behave like corporation and a corporation can behave like a government. The key is whether interactions are voluntary.

The question of whether we can 'live without a state' is really a question of whether individual humans can regulate bad actors through culture and decisionmaking rather than codified rulesets and presumed authority to enforce punishments. My family has some codified rulesets to allow for clarity and communication and pre-emptively resolving disputes, and very little punishment from presumed authority. It doesn't work perfectly.

Wherever heirarchies are organized among humans, we can see a few truths:

TLDR In the status quo, there are some heirarchies organized among humans that shouldn't exist. Some of them we call 'states'. Fight those. There are some heirarchies organized among humans that should exist (partnerships / division of labor). Support them.
