One of the big needs I expect is when the confiscations begin, there will be a rush into crypto-currencies.
Early bitcoin enthusiasts appreciated this (the threat of confiscations in particular, or totalitarian governments in more general terms) from day 1.
The more totalitarian governments also appreciate this; they see bitcoin as a threat for this reason, and so they move against bitcoin sooner rather than later.
The less totalitarian governments (I include the US here) have no immediate plans to do any crazy-ass confiscations. But, if and when they decide to borrow a page from FDR ... it will be too late. Bitcoin will be entrenched.
Most people won't appreciate all of this until it hits them over the head, at which time they will make Satoshi a saint.
