can't i just pay 2.50 btc to get the space food (hope it's tacos) and then stay here on Earth

can't i just pay .007 btc to get the mcfood and then stay here on Earth
mcfood? = Yummy chemicals?
By the time Satoshi returns your .007 btc might buy you enough Steak and Lobster to last a week or more.
Can you imagine buying this for only 0.001 BTC?
Yeah, this picture actually make me feel hungry :/
