Is the moving van scenario one where there are lots of other spots available nearby, but you really need this specific one? In that case, maybe. Your shooing should be appropriately apologetic. And also, if the other car has even a minimal reason to prefer this spot, then imo that minimal reason may be enough outweigh your strong reason.
If it's the only spot left nearby, then moving vans get no special privileges.
