It's just the paradox of tolerance again. Too much freedom causes a power vacuum, which almost inevitably causes some small but determined authoritarian group to gobble up that power until they get so big they can overthrow the whole system. And then you're back to square one, except now the system is probably fascist.
How do you you "gobble up power" in a group dedicated to preventing anyone having power over others?
That group won't exist in a vacuum. It needs to be resilient to outside interference. Even inside that group there are going to be people that only identify with it out of convenience rather than true belief. It is still possible for individuals to accrue social capital, form "inner circles" and individually stockpile resources - and stopping them would logically infringe on their freedoms to associate, freedom to dig holes, etc.
Right "libertarians" are more susceptible to power vacuums, provably so, with so many experiments going down the same way. Reason for that is that they aren't really against authority, just not their kind of authority.
If you aren't entrenching the need for active resistance to power and hierarchy, you are expected to fall the same way, that kind of attitude is very much present in actual anarchists, left anarchists.
almost inevitably
as if you're basing this off of some historical examples instead of just regurgitating the same bullshit argument you've heard repeated a million times...
the paradox of tolerance is about tolerating intolerant groups... not about maintaining some good powerful group to prevent some other bad group from taking power.
It requires us to ignore the government and begin setting up the systems and communities we want and need.
What's that
Libertarian Socialism specifies a wide range of systems of political stances that include most if not all forms of Anarchism (excluding AnCaps, if they weren't already), some varieties of democratic socialism, classical libertarianism, etc. It does not include liberalism, laissez-faireism (what some refer to as "libertarianism"), Social democracy, MLism, or any ML-adjacent ideologies.
what, "oxymoron"?
