What impact does this have on contracts in general?
When I give my word, I keep it. When I sign a contract, I honor it. There's a social contract that assures me that the counter party will too. There's a court system setup to ensure they do. There is force behind that if it is taken even further.
If I should instead shape every contract with a 20% hedge that assumes the counter party will not keep their word, doesn't that introduce a significant amount of inefficiency in the entire system.
Isn't it long term better and in fact just that those who give their word, spend all of their money and then run out take the consequences of it?
For systemic risk to be properly moderated, the individuals or even individual counties must suffer the consequences of their actions. You can opt to not allow this, but you ultimately suffer as a whole when you do.
I see no better way through. Do you?
