The current bitcoin model can't stop people from doing stupid things.  Like dealing with a group that has had issue with reliability for years. Like storing bitcoins on an exchange, pool or somewhere else where you don't have the private keys. Like designing software  that allows one to withdraw the same funds many times.

This isn't about the bitcoin model, this is about gox being stupid, uninformed, or criminal depending on who you believe and people not seeing (or ignoring) the repeated issues all through 2013 and before.
