How did you come to your understanding of anarchy if I may ask?
I’ve heard of specific cases of organization without leadership such as in the case of co-op companies but I’ve not heard it in the framework of anarchy really.
Personally, I feel there are some unique challenges with not having an organized government with representatives. I feel that a good system relies on having an educated populace to make decisions effectively; this is a current issue even in representative governments, like the US, since in many countries voters aren’t required to be educated to be making decisions.
Another issue is creating incentives to work and to strive for higher achievement. Big architectural projects may require people pooling resources even from those that would not personally benefit, as an example. Some people choose to what they do because they feel properly rewarded for the effort, I think having a minimum bar of care for everyone makes sense, but the people contributing more may want more in return if you’re going to try to sell them on your idea.
