You are wrong, in many cases the customer has no recourse for credit card fraud: https://news.ycombinator.com/item?id=8918865 People think credit card anti-fraud measures are perfect. They are not.
I don't think anything is perfect, but with BTC there is a 0% chance of recourse. I'll take the option with a ton of consumer protection law and someone to sue over the Wild West any day of the week.
These consumer protection laws protect you regardless of the manner of payment: bitcoins/dollars/whatever.
You CAN and SHOULD use the legal tools at your disposition (lawsuit, small claim court, FTC/BBB complaints...) if you get scammed after paying in bitcoins. You definitively have a chance of recourse. These tools work, that's why we have them.
For example the U.S. Securities Exchange Commission successfully prosecuted Trendon Shavers (he was running his scam denominated in bitcoins).
