There is a large cost to building out excess capacity to handle peak demands. That cost gets passed on to customers, and everyone ends up paying more for electricity. There’s also an environmental cost, as “peaker” plants typically burn fossil fuels. Even building grid-scale storage solutions would have a fairly large environmental impact (assuming that’s even feasible at all on the scale necessary). It makes sense to target both the supply and demand sides of energy consumption.
