That's the only reason why I would consider to buy that card but won't use it for the original purpose to store any coins on it, because of the above mentioned things...
The card is pretty cool looking but that's all, you can't stop the greed, if this card becomes widespread among people, sometime an employee of the company will realize how much bitcoins are loaded to the cards and their system is developed by humans, and humans are greedy... They will find a way to take some bitcoins, not all bitcoins of course, but that's the way life is...
So it will remain a fancy collectible thing for bitcoin lovers
