A variety of reasons. Two things to consider:


 * If people had unlimited renames and would do it every week, that would create a huge strain on the back office and create queues for this task and others. Because a lot of stuff needs to be moved for a pagename.
 * In line with the moving: if you change your username, your old username and its contributions become redirects to your new name. If the userpage is moved a second time, those old redirects point to another redirect, giving you tons of double redirects across Wikia. It doesn't break anything, but it does create a mess.
