It seems to me that technology is the only way to achieve true anarchism.
I know that a lot of anarcho-transhumanists/antechs are leftist, but honestly technology could lead to the means of production becoming robots that are cryptographically verified as belonging to you, so private property would be able to defend itself. Capitalism is an economic technology itself. I think in the future, we could all be capitalists and design shit and then use our personal robot workers to make stuff to sell to each other, in a totally mutual capitalist economy, and there would also be a lot of things people could make with 3D printers/additive manufacturing machines once they get really advanced. Sounds absurd now, but with how fast companies in China are automating shit, it's the long term trend and it seems like it's not super far off now. Some statists are starting to use this to argue for UBI or even communism, but I think the end of direct work will actually involve widespread advancement into everyone being capitalistic. Even now a lot of people work from their computers, a means of production they own.
Another thing is that with full automation welfare wouldn't be needed, because charity would become exponential (sort of, it would be limited by resources and land obviously), since as soon as you can get a human level robot and a super-advanced 3D printer, you get free income from the capital you own, and can then use that to gather resources and energy to build more robots, so everyone's living standards would shoot way up, and things would get pretty comfy.
The primary sticking block to anarcho-capitalism is that most people are too weak for it, but with technology that could change, because things would be a lot cheaper, and there would be high levels of automation, but potentially down the line due to transhumanism meaning that rugged individualism doesn't involve a massive culling of people who aren't rugged enough for it. That's the only way I can see the majority of the public eventually coming round to anarcho-capitalism and slowly abandoning statism, because most people want to be free, they are just too weak and frightened to be anything but slaves to politicians.
Obviously, wealth inequality would increase massively with transhumanism, but none of that shit matters if living standards as a whole rise massively, and the incapable are able to gain new capabilities through technology.
So, I think we'll have to wait a while until an anarchist society is likely, but in the meantime we should probably make sure that we at least push back against centralized militaristic government so that we don't get some kind of skynet scenario due to the military industrial complex. Statism would make AI more dangerous because it would centralize it and put in control of more things, leaving no counterbalancing intelligence. The libertarian party should probably promote upcoming technologies as solutions to the government problem. If you think about it, cryptocurrencies and existing (if shitty) 3D printers are just the start of that movement. That's going to be the successful way of getting libertarianism to be popular, in preparation for future technologies that make take us to anarchy.
We definitely shouldn't let commies monopolize the full automation meme, otherwise they'll be positioned politically to take over later in this Century.
