I would generally agree if we never just went through a major crisis and saw the failings of current processes. One of the things that was made explicitly clear, is that for some firms that are too large, the bankruptcy proceedings don't really work like they should. I do think, however, that if Google or Amazon failed there are some elements that would stay up - but it's more than just those elements. It's the little things, like email for 200million people disappearing overnight. I can't even imagine the amounts of things that would be lost (receipts from sales, tax information, customer data, invoices, legal contracts, etc.). Much less just a major communication channel going dark. That alone would cause a dip in GDP (in my opinion). Might be difficult to foresee, but so was the banking crisis.
