Perhaps for your use but for many others it's not so silly given that the actual image can be changed simply by editing the submission after approval. You could also try running any type of photo contest and see how many people try to move their images directly to the "winners" category once they figure out they can... then there's the stubborn members that decide they want their photo in an unrelated category and continually try to move it despite admin putting it in the appropriate one in the first place. Unmoderated image editing may work for your site and audience but for many others it would be a huge risk.
