Gonna throw some ideas.
We need more distributed propaganda and more subtle propaganda. We need to produce articles, drawings, memes, mangas, enternainment, movies, videogames, that are not in-your-face political but that have a liberty-oriented and subtle political messages.
Also instead of working in the private sector like some cucks, we should work in the public sector, infiltrate all the universities and all institutions, make friends only with our own kind and make them all kind of favors (government contracts, promotions, nepotism), seize all the money the State spend on "cultural activities" to promote anti-Statist ideas. We must infiltrate schools and be the one that decide what people teach the youngsters, and they will be taught about the price system and why the market can't fail and why the State is evil. Not easy on the soul, but it's the difference between surviving and dying.
Also we must remove those who ruin our aestethic. For example the other night a stream for a libertarian channel called Academic Agent or something popped up, and he was having a live stream discussing with a chubby female, with short hair and a fuckin pet lizard on her shoulder. Her opinions were also shit and incompatible with libertarianism or anarcho-capitalism (she was in favor of death penalty, and in favor of death penalty for public gays).
Those kind of people must be removed, we must have good aestethic all the time.
We also must support the removal of people who don't agree with our agenda, do everything in our power to destroy them. Exactly what leftists would do. Also we must support organizations that works for secession, since secession is a great way to diminish the power of the State due to the creation of a mutitude of micro-states that are then forced to compete with each other.
Good thing with this plan is that even if we fail to remove the State, at least we won't get cucked and we will get a shitload of money from the cucks who love the State anyway.
All the people who did something for liberty, like Thatcher or Einaudi worked in the State and for the State. They influenced it in order to create laws that would self-limit its power or guarantee the respect of natural rights. They didn't manage to have a perfect record, but they did what they can. I don't see them as heroes, but they did a lot.
Unless we get the exclusive use of an extremely powerful military technology, we will never have the power to remove the State, so we need to shrink it slowly by infiltrating all levels of society.
