I think the big difference with this logic though is the weight and cost of the batteries as it stands now and in the foreseeable future.
If you are always hauling around a huge battery pack and only need it for road trips a couple times a year, the rest of the time you are wasting efficiency and energy by hauling around all that extra weight. That and all those extra batteries to give you that range cost a lot more making the car that much more expensive.
The best way to solve this issue in the near term is to increase efficiency and improve charging curves to make "filling up" as fast as possible, not just add more batteries and more range.
That said, long term we should see improvements in battery density that will ultimately mean more range out of the same or less batteries which helps give more range for hopefully less cost up front.
We are all definitely still early adopters in the EV world and I love it! It will definitely improve over time, and I think we will likely see more affordable lower range cars in the future since many people don't need cars with 500 miles of range for regular driving. But I think to increase adoption of EVs as a whole, people that aren't familiar with them or are nervous about range will be sold much easier on EVs if they can get a car with huge range to ease their anxiety about running out of juice. But then they will realize soon after that they could have easily gotten by with 300 miles of range
