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).
