The energy grid is fundamentally a battery, it would be asinine to have distributed battery sources storing energy for individual units when literally everybody is connected by a giant battery. The fact that it's not super profitable to store energy isn't a failure of the energy system, but the economic system that the grid must adhere to.

It's not a battery. It's a set of generation sources that have to be ramped up and down to meet demand. And ramping up variable sources to meet peak demand times tends to be expensive for the grid.
