Talking about non violent solutions is also a bit of a luxury problem. I'm not at all certain that no conflict of interest will occur about some basic necessities of life, such as drinking water for example. I'm also not that confident that the peaceful solution will prevail when things go sour even a little bit. The sustainability of the rapid growth of human population is another thing I'm not very certain of, but that might partly be caused by me having grown up in rather densely populated country. I'm bearish about the organization, structure and philosophies of most current market-leader countries and I've been expecting an economic "crisis" on a far bigger scale than the one we're in at the moment, for quite a while now.
From what I gather even though the current human species is a lot older than our recorded history, our modern civilization and success coincides with the recent period of unusual stable climate (from the last ice-age up till now). In that regard I don't have high hopes that our current specialized system of food production is very robust against even small climate changes which are bound to happen, pollution or not. I wonder what'll remain of human civilization and sensibilities once the going gets though. Of course I don't know if we'll life to see changes on that scale, but I'm hearing signals of a change from several different sources, from studies of repeating patterns in history (some matching it to some kind of 300 year or so climate cycle of our sun), right up to NASA predicting imminent climate changes based on their measurements. Curiously most seem to suggest things will start to get interesting sooner rather than later with estimates from the latter part of 2014 or 2015 extrapolated from patterns in human-history and NASA estimating a tipping point in climate change around the 2025 mark.
So for me the efforts to create robust, self-regenerative, corruption resistant means of communication and collaboration are also partly motivated out of hope to create a framework to help overcome bad times. In that regard I hope the short term estimates of 2015 are wrong, because I think of open-source, bitcoin, bitshares-dacs and the like as only the first small steps and I don't think they've penetrated human consciousness and culture far enough to cope with the effects of a short term more significant global downtrend.
