No problem at all. I guess in a world where you will never ever never part with your bitcoins, then the ability to spend them without any pain, strain, fuss, muss, bother, wear, or tear might not matter to you.
But to me -- and, I would assume, to most of the populace -- money is not and end in itself, but rather a tool with which to achieve one's goals. Money unspent upon one's death is money that has served you no purpose. I plan on spending some of my bitcoin before I die. You gonna croak with all of yours as unrealized potential?
Plus, it neatly solves the repeated dilemma of the conversation with the bitcoin skeptic:
Skeptic: "Well, what good is your magic internet money when nobody accepts it? I mean really, where can you spend that shit?"
Shift Card holder: "Anywhere that takes Visa"
Skeptic: "Oooooohhhh...."
