You seem to conflate [1 - what I want FB to do with regards to privacy] with [2 - what FB needs to do so I trust they won't steal my money]. The two have nothing to do with each other.
Realistically speaking, 1 may never happen, 2 is already there (even if you're only liable for $50 from unauthorized cc transactions).
