At the same time, a physical bookstore doesn't force me into storing my copy of their book in one specific bookcase by making it impossible to move my books from my loungeroom bookcase to my bedroom bookcase.
If you're going to put DRM hurdles in my way to make it difficult to move a book I "bought" from you between my phone, my tablet, my ereader, and my laptop; then yeah - I'll get outraged at you when you refuse to allow me to redownload it. I never asked for "infinite additional copies", B&N are forcing that requirement on people who need to move DRMed files between devices.
