Is asymetric cost benefit rapeing trustworthiness of the Internet?

Over the past two years a have been dealing more and more with computers. Hell my major had a great deal to do with computers, but thats not new to anyone. In this day in age everyone and thier mothers has a computer(except David), and as time goes by we become more dependent on computers and the internet. So what happens if one day the internet crashes? Bussiness will topple, banks will go ballistic, people will (to put it roughly) fucking freak out!!! Wide spread pandamonium right?! Y2K, but with real consequences.
But what if i told you that it could be averted. What if i told you all it would take if for ISP's (Internet Service Providers) to implement a new internet protocol such as IPv6, that would greatly limit a hackers ability to evade being discovered when hiding behind differnt digital identities. Well IPv6 exists and it can be implemented, but they wont do it. Do you know why? Because thier not the ones at risk of financial loss, the sites being attacked by hackers are. Hence the asymetircal cost benefit. So its basically the "If it doesn't affect me then i dont really care" mind set that cripples some many things in this mostly uncaring world. Its sad, really sad.
