Yes, my point is, that applies for a single coin. The conceptual shift I'm talking about here is that (my definition of fork here is) /another/ coin. Another coin (like ethereum, doge, whatever) is just another "fork" of "cryptocoin-coin". People in need of cryptocoins, if only one existed, would acquire, buy, mine that one. But now that they have multiple options, it is split between all, to varying degrees. As long as they are interchangeable, they are the same thing pretty much. In a fully cryptocoin future world, when a dogecoin is minted, it affects the value of bitcoin. So any x-coin does not live in a vacuum, and can only be scarce in its own network.
