You don't understand the problem. When it comes to smart contracts we need RAM not DISK and they don't make individual machines capable of 3000TB of RAM and cluster support isn't ready.
Furthermore, you didn't grasp the point of the article was to come up with a pricing algorithm that ensures there can never be a "run on the memory bank".
How is cluster support isn't ready? What if you find a nice vendor like Cray?
