I see what you mean. I had envisioned every gas station gradually converting to a charging station. You‘re right - with most folks charging at home most of the time, far fewer charging stations will be needed compared to gas stations.
Which leads to what could be a transformative issue over time. Massive amounts of real estate are devoted to gas stations. Interstate exits often have 4 or more gas stations competing for business. As the need for them decreases, how can that land be repurposed? We only need so many “convenience stores”. Nowhere near an immediate problem, but a sea change is coming.
