Your second point doesn't necessarily derive from the first.

I can understand standardizing on only one cryptocurrency, but why not one that addresses many of Bitcoins' limitations?

I'm not saying it should be Dogecoin, actually I hope not, but it could be.

I agree that the one cryptocurrency doesn't have to be Bitcoin. What I left unsaid is that so far none of the altcoins provide enough improvement over Bitcoin that it's worth breaking compatibility.
