Right: a vendor's not forced to care whether any bitcoin they accept was stolen, but they are forced to care whether a credit card they accept was stolen. Doing a sufficiently shitty job of keeping out purchases with stolen cards can literally end a business, in a hurry. Meanwhile nothing's going to happen about stolen bitcoin you accept—probably you'll never even know—unless there's an actual police investigation you get wrapped up in. In that respect, it's more cash-like.
