>The odds that one or more sites you use end up leaking your plaintext passwords is far more likely than Lastpass being hacked

I'm not sure this is a fair generalization, especially without knowing the sites sthreet visits. Lastpass holds thousands of passwords and is probably a pretty big target for hackers. I don't doubt that they have great security, but nothing is guaranteed; one should at least admit that trusting Lastpass as a SPOF is a non-trivial decision to make.
