I've been considering some of the arguments in this piece. Section 2 covers co-ordination problems (why boycotts don't work etc), and I wondered if the following solution could work as co-ordination tool without the need for state law. Let's say a polling tool is available, whereby passionate people can request a public call to action on some issue. But the agreed action is not taken until some specified critical mass supports the action. When that critical mass is reached, all participants know that their action will be effective, and the action goes ahead successfully. For example, it might be boycotting a consumer product for a month, which is more than the company can bear, but which is not a difficult (and only temporary) sacrifice for each individual. This might overcome the hurdle of people not willing to make a sacrifice when they are uncertain others will act similarly and that their sacrifice will be meaningful. Thoughts?
