Imagine if every body had a bond and arbitration agent on file with the block chain. Imagine everyone refused to do business with someone who had an unpaid judgement against them because their own bond was at risk if they did.
BitShares is the foundation of a non-violent consensus on property rights that replaces the use of force to physically reallocate property.
I'm sorry, I am not a libertarian. These non-violent consensuses are an utopia. Even blockchain technology won't change this.
In my point of view there are always situations in which one has to be violent or at least punish people by some consequences.
For example, imagine there are some farmers, who can live autarkic, i.e. they produce everything they need by themselves and do not need to deal with anyone else. Imagine further, their favourite activity is to rape your kids. What would u do? Wait until they want to deal with someone else or would u go over there and cut off their balls?
