Some people do not have the computational power to generate and store millions of them efficiently.

It may be true that not everyone has the computing power to generate a large amount of private keys in a short period of time, but those who would require such a thing certainly do. But what do you mean by "store"? A Bitcoin private key is just a 256-bit number, that's 32 bytes only. You can store millions of private keys on any memory storage device, even on low-budget USB sticks or memory cards that cost no more than a few bucks.

Also, no need to resell the same ones over and over again, as I can generate 500 million of them in around half a day.

There is no way to verify that you won't sell the same keys to multiple people or keep them for yourself. Again, such keys are useless for any practical purpose.
