Certainly such a model is regressive, but it is in line with the actual costs of service. In my opinion, it's better to have a pricing model that reflects the actual costs of service, then an explicit subsidy to repair the regressivity issue, such as the Consumers Affordable Resource for Energy (CARE) Program in California.
Using usage as a proxy for value-received from the grid worked fine when there was a monopoly provider, but with distributed solar being a thing, we have to move off of the model, or we end up with an even more regressive system. As I noted before, we use these systems for water, gas, and other utilities, so we have methods for addressing their natural regressiveness.
Alternately, if you feel (and this is reasonable) that power should be a ubiquitous service provided to everyone, take over the grid, pay for maintenance and development of the grid with tax dollars, and bill only for generation/usage after a reasonable base allocation.
