It can't have gone : I will explain this sentence. We do not know where it go or not. And I strongly believe that it still stay.
When I know correctly, then following is possible ?
I placed my wallet here. But it disappeared. It can't have gone with legs (1).
Frequently we say "It goes since it has leg ?" or "It fly because it has wings ?" when our things are disappeared. Here we know the fact that wallet can not have legs so that we can use (1) ?
