It's too broad.

Let's say I have a method name 'loadResourceFromBlarg()' and I'm programming with 
Eclipse or NetBeans or one of those editors. Now I could use Ctrl-space to get code 
completion, but if there are a number of 'loadResourceFromXxx()' methods, the completion 
list might take time. If there are many calls to the method of choice, I'll likely copy the 
method name once into the clipboard and repeatedly paste it.

Let's say I'm importing static a bunch of members from a utility class.

import static junit.framework.Assert.assertEquals
import static junit.framework.Assert.assertNotNull;
import static junit.framework.Assert.assertNotSame;
import static junit.framework.Assert.assertTrue;

It's much faster to copy "import static junit.framework.Assert.assert", repeatedly paste it 
and just type the part that varies.

This type of thing comes up a *lot*, so I copy and paste on a regular and frequent 
basis. This has nothing to do with the refactoring of which you spoke.

You're assertion was ridiculous because it banned legitimate uses of copy-paste.
