Agreed - scrapping furniture just because you're moving is not a great idea. This will, however, occur often when we buy IKEA furniture (or items of that quality level) that we often have to trash items, or are actually trashed accidentally during a move (think one of their flimsy dressers or wardrobes).
It's a wasteful practice, and an important part of our mission is to keep furniture out of the landfills. That starts by getting as many uses out of the furniture that we can, before it stops working for us, either visually or functionally.
