The whole point of trying to make a GPU-hard coin is to get a more even initial coin distribution than bitcoin/litecoin did.  The number of people with CPUs is way higher than the number with good GPUs.  There is no point to making a new alt-coin to change the mining algorithm if it doesn't promote a wider distribution by cutting out the GPU farmers.  The algorithm doesn't have to last forever; it only has to last a few years until ASICs are developed.  Litecoin lost its whole purpose when it was taken over by GPUs.  If we knew a way to assign an equal amount of coins to everyone on the planet in a decentralized way, we would do that, but that technology is decades away.  Distributing it to everyone with a CPU is way less fair, but it is still vastly superior to giving it to everyone with a GPU.
