My main problem is that I don't see a satisfactory way for me as an individual to safeguard a wallet. Cold storage is an interesting concept for an exchange, but it still seems fundamentally inferior to normal banking's procedures for undoing fraudulent transactions. N-of-m encryption schemes are nice, but they only really make sense if you have each of the keys in a different hardware crypto device. Even then, in practice I suspect all of the exchanges are set up such that 95% of their cold storage is accessible via machines that are connected to the public Internet. (I'd be interested in independent audits that show otherwise.)
