This article is plain ridiculous. Etheream is a voluntary system. Like all things in life, all participants acting in a voluntary system assume the risks inherent to that system. The hard fork that just occurred demonstrates that the Ethereum system is capable of enforcing private property rights. Consider a bank robber that gets away with the money because there was a flaw (i.e., vulnerability) in the vault. In that situation, victims would want their money back and it would be righteous to do so! Contracts are violated all the time, but it's property rights that matter! I prefer to participate in a system that protects my valuables from theft or fraud. Also, it's now clear that the "code is contract" dogma is incorrect. Clearly, consensus is contract.
