I guess the most prominent breaking point at the moment is cost of living, prices of fuel and food etc. Perhaps we are only another year or two away from worldwide riots related to food & petrol costs?
Which suggests if you can get involved in a self sufficient community that produces its own food etc then you may be able to shield yourself from upcoming hardship.. and that self sufficient community should use Bitcoin
Ultimately I would like to see a situation where each 'self sufficient community', and other bodies who have something of potential value, issue their own crypto-currency. If the organization is managed well (including how it's currency solution is implemented and maintained) then it's monetary system prospers and the members who make up the organization benefit.
I hope that Bitcoin offers something of a proof of concept to inspire movement toward the aforementioned scenario, but have to admit that things could be somewhat prettier than what we are seeing in Bitcoin-land these days. Oh well.
