Designing or intending a system to be used at massive scale is not the same as building and deploying it so that it only initially runs at that massive scale.
That's just a recipe for disaster, "We don't even know if we can handle 100 users, let's now force 1 million people to use the system simultaneously." Even WhatsApp couldn't handle hundreds of millions of users on the day it was first released, nor did it attempt to. You build out slowly and make sure things work, at least if you're competent and sane.
