Take this thread as purely hypotetical but try take it somewhat seriously.
Toward the stereotype NFs are people that are most likely to be concerned about human rights. Also they make almost 10% of the worlds population.
What is about 700 000 000 NFs .
Plus you are scattered around all world. What means that you are pretty much everywhere. There is no a single country that does not have NFs in its population.
What means that if you manage to connect enough NFs you would have the power to change the world. (even on none violant ways). Especially since many others would probably join you in this endevour.
I mean from strategic point of view it can be done.
For example developed countries tend to be democratic. What means that taking controle over them is probably the easiest move if you manage to mobilize enough people (that by the way tend to like NF life philosophy for the most part). Basicly the only real opponent are multi-national corporations
What makes this a good first move for the movement. However you must not do things in secret since that will turn people of.
Once you have most of the developed world and its resources it should not be that hard to remove the third world dictators and international organized crime if you really try hard enough.
So, why NFs don't do this ?
Ok the idea is crazy but with enough strategic planning and determination it would not be impossible to do achive this goal with time
