You mean, if only there was an economically viable way to store electricity. Still waiting on that one.

Batteries. Economic viability is the next argument when you externalise the true cost (carbon).

Carbon is not the only possible cost to the environment. Building batteries is not exactly easy on the planet either.

You mine a resource (lithium), that can be recycled endlessly with very little loss.

You are right about Cobalt, but it is already being reduced/removed.

It's not even comparable to fossil fuel mining (even though technically it is fossil fuel mining). Because it's recyclable, so we aren't "losing" any material, in the form of converting it to an unproductive/hazardous byproduct.
