It's the same as photocopying a print book -- also copyrighted, but can be shared in the original form because the number of copies stays the same. It's possible that some people truly don't understand the distinction.
The way computers work and the ease of copying files may well confuse the issue [especially for those who don't want to understand]. There's no real way to "loan an original" bought-and-paid-for ebook unless you loan the device it's stored on. "Sharing" it by putting it on some other medium (flash/thumb drive, CD, sending it in an email) makes a copy, and the only way that can possibly be legal is if the original file is immediately deleted.

It's possible to "move" a file - in the MSWindows finder, you hold down the shift key while you drag-and-drop - and this just tells the computer to delete the original once the copy has been successfully made. But probably just about no one does that.
