I thought this too, but then, due to my lame password management, my mtgox account got owned and they took out around $250. Oh well. Easy come easy go. But what I learned is that bitcoins really are like cash. You lose it, and you won't get it back. 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.
