It's called cut and paste (2 actions), not "move" or otherwise. Being consistent with decades of software usage is more important that whatever you think is "broken" or not, because that's not actually the case, just another model of how to do things. The Excel example is particularly interesting, Excel does something similar, so when you "cut" ("ghost" version) and paste in a cell that overlaps with the range being cut, it breaks completely, which it wouldn't if it did the simple "remove cells, put them somewhere in memory, paste them to new location".
