Right. I get the social equality aspects of the argument, but charging the fully burdened price for energy (i.e. which includes time of use) seems like a good way to get people to conserve smartly instead of wasting resources. It
does make sense to turn down the A/C a bit when the grid is stressed, but there's literally no incentive to do so without some sort of realtime pricing. In fact, it makes MORE sense from an
individual standpoint to turn it up as strong as it can be so if the power does go out, your house will stay cool a bit longer. That, collectively,
increases the probability of the grid going out. It's a collective action problem, and without some sort of incentive to conserve use and greatest demand, it increases costs, emissions, and fragility of the grid.
It's good that wealthy people install solar and batteries to only use grid power in the cheapest of times. We literally want to incentivize wealth being put to productive use (in this case, reducing stress on the grid and--in the case of solar especially--emissions). That means more resources for others.
