EV economics are a little bit odd. The difference in cost between a base model and a luxury model is smaller than the difference between a short-range and long-range model, just because of how expensive batteries are. Manufacturers are, no doubt, keenly aware of this.

If a manufacturer released the stripped down, no-frills car you're describing, a competitor would release a competing car with all the bells and whistles and slightly less range at the same price-point.
