And if you feel that way, every voting system probably allows for it - the one I intend to use certainly allows it. But if you'd prefer to cast a vote of the style "both of them, or neither", then an individual vote won't do.
Worse, individual votes can end in paradoxes. Say that we have two options, A & B. A receives a majority, as does B, but A & B together fail, so now I have to implement both and not implement them together. Fun times.
And before you tell me that I shouldn't allow the vote "A & B together, but neither individually", let me stop you right there and state, clearly and unambiguously, that as long as I am the curator, I will never restrict the votes someone can express. And yes, I have had people who wanted combination of options but not their individual components. This is not theoretical.
ETA: see this post for the upcoming vote
