I've always believed Elizabeth wasn't talking about material possessions as much as she was simply commenting on the fleeting nature of time and life, of how the "possessions" of her life were completely temporary and insignificant in comparison to the span of history, which she was always keenly aware of.

I hope I don't leave a beautiful corpse, either. I hope it's old, wrinked, worn out, and exhausted from a life fully and completely lived. Heck, I'm only 45, but I'm already halfway there on most of those, except possibly wrinkled. And that's only because I withstand sun well. Here's to people looking down at me in the coffin when I'm 110 and saying, "God, she was old. Check out that skin on her neck."
