Yeah, I know those arguments. I like the overcapacity approach, but policymakers seem to struggle with it. In principle you could install a world-circling transmission grid and obviate the need for storage entirely. But long distance transmission carries its own risks and costs. The radius of loss arising from adverse events goes up a lot, for example. And new-build long-distance projects take decades, which we can ill afford. In the world in which we live, storage will be important and there is no panacea.
