Why would you even do this? Information I don't want others to get at, I keep in my head. It being on your computer is merely slightly more secure than it being on a server somewhere on the internet. We all take risks of less than 100% secure. When you use your credit card, how confident are you that they don't keep and store said credit card in their 'cloud'?

The market does always correct itself, even if it is in 25-50-100 year cycles. The problem is that these corrections are extremely volatile, causing mass job losses, hunger, homelessness, death, etc. Thats why we need a balanced approach to economics. So we can allow for as much freedom as possible to innovate, build a business, or whatever, all the while mitigating monopolies, too large to fail, and market volatility when shit goes wrong.

Personally, even if things are too large to fail, they should fail anyway. Let it completely fail, if said business is important to government (such as banks, but not trade managing companies) then government should create a brand new replacement (nothing at all comes from the previous business except non-management personnel). When the volatility passes, said business slowing fades out, maybe even getting bought by companies that survived the bad weather.
