Dear writers: there's a difference between "just can't" and "can't just". In "just can't", "just" is an intensifier - the speaker is emphasizing the inability to do whatever "can't" modifies. In "can't just", "just" isolates whatever "can't" modifies; you have to do something else also. E.g.:
"We just can't leave him here!" - "It's imperative that we take him with us." (We are especially unable to leave him here.)
"We can't just leave him here!" - "We have to do something for him before we go." (We can't only leave him here and do nothing else for him.)
