You did not oppose centralised bodies for certain tasks, such as providing security or doctor.
Where did you get that, I didn't said such thing...
The truth is the we can't even imagine how a free society would look like because we haven't had one ,certainly not in our lifetimes. But we have to remember that the government is only 6000 years old, there wasn't really a government before that, so there is no reason to think that it's a permanent establishment. It may have a role now, but as technology progresses, and many state services get replaced by voluntary ones, their role can quickly diminish, and they could go away just as they came to be.
I may have understood you wrongly, the comments I base my comment on is this one:

I think we have some anarchistic communities; They may be small, but they are real. For instance Freetown Christiania in Copenhagen Denmark: https://en.wikipedia.org/wiki/Freetown_Christiania
In Netherlands we have ADM (just outside Amsterdam): https://adm.amsterdam/
We have another community close to Amsterdam called Ruigoord; This community is maybe lesser of a community in the sense of a living community, since it is for instance not allowed to live at Ruigoord. It is more like a cultural free haven: https://en.wikipedia.org/wiki/Ruigoord (their website is in Dutch only http://ruigoord.nl/)
I know both ADM and Ruigoord and visit these places regularly, They are free havens in sense police and all are not entering the premisses. They have to obey some rules, such as no big sound after midnight (Ruigoord has many cultural and music events), but in essence what happens on the premisses is considered private and not under law enforcement control. With ADM what I see that most people living their are not Dutch people, but people from other countries. Interesting is that ADM already exist for so many years (20 years already I think) that the community have members who did not live anywhere else in their lives and now are allowed to vote, ie being a grown up.
I think you misunderstood me, I have said there that anarchy is my view is a decentralized community. I described the exact same thing in this article. It's the same thing:
I am curious about Christiania, I have heard about that. I am curious how taxes work there.
For instance if you earn money there inside that zone, do you have to declare that income?
What is the level of "anarchy" exactly in that zone?
That are really good questions to which I do not have answers to be honest. With some further internet research, the answer may be revealed :) They apparently bought the place some years ago from the local government.
Regarding taxes, I even don't know how it is at ADM here just outside Amsterdam. I go there a couple of times a year when they have their music and art festivals. Super nice! Next time I'll ask the people who live there.
In the mid 90s I was at a similar place in Maribor (Slovenia), Pekarna, also a free haven, quite small, but again a place where people lived forming their own community, and where the police would never step a foot insight, so anything goes, whatever you felt like. http://www.pekarna.net/node/17
You know of the existence of the mini states? Micronations they are called. These are self proclaimed countries with their own flag, currency and all. They do all the things that are required to be a country. The only thing they generally don't have, is the recognition being a country by all the other countries in the world. There are micronations on oil rigs, on small islands, and so on. https://en.wikipedia.org/wiki/List_of_micronations
