Most of the people of the world can't really save either. Cash loses value over time, gold is hard to validate and keep safe, and is even banned in lots of places. Bitcoin to the rescue! Now everyone can start saving, and even be rewarded for that.
I could go on all day long, the benefits are endless. Just live in a shitty country for some time and you'll figure it out pretty fast.
Yeah cause internet access and a modern computer are waaaaay more common than bank accounts or prepaid credit cards....
According to wolfram alpha, there are 1.871 billion children age 15 or younger: http://www.wolframalpha.com/input/?i=population+under+15
Those 1.871 billion children literally determine the future. And all of them can currently use bitcoin for buying anything available via bitcoin. That includes Humble Bundles, for example, not just drugs. Though admittedly they'll still just pirate most videogames rather than buy them. But they won't be able to pirate MMO's, and it's a matter of time before MMOs begin accepting bitcoins.
Digging around, I found they're almost equal actually, and cellphone users vastly outnumber bank account holders (cell phone users exceed toilet access !!!).
50% of adults worldwide have an account at a formal financial institution.
60% of adults worldwide have internet access, with 39% having home internet access (the remainder having shared or limited internet access).
80% of adults have cell phone access.

I believe that what is pushing Bitcoins value is that many people call it "the credit card of the 21st century" and they are buying bitcoins as shares of the next Visa.
EDIT: as wildgift said, there is no insurance in Bitcoin yet, but I'm sure that if Bitcoin starts being really popular we are going to start seeing online wallets with insurance provided by big corporations. CCs (as a technology) don't include insurance either...
That's what's different with Visa - there's an element of insurance with a credit card, and that is greater than what you get with a bank's checking account.
The insurance of being able to cancel a check is what you get with a regular checking account, and that's greater safety than what you get with bitcoin.
Of course, there's a price to this insurance, and it's the fees, which are much higher than what you pay for bitcoin transactions.
