Is there any reason to have it running constantly?

Yes.  I use Dropbox for work, so exiting and restarting the client all day long would be just as inconvenient as these pop-ups.  My Dropbox also contains a large number of source code files.  They're small in size but the Dropbox client takes a long time to index them on startup.  Not to mention the fact that one of the key selling points of the product is that it runs in the background, making cloud storage as convenient as a folder on your computer.
