Infrastructure needs depend on how the car is used. I have a basic level 1 charger (120v/15a household outlet) and so far have used public chargers zero times. There has only been one time where I didn’t have enough charge for back to back trips to the next major city over, and had to rely on our second (ICE) car. Could have been avoided with a better charger. I have been hitting ~700 miles per month. One thing to keep in mind is that you just need enough charge to get to your destination and back. Going to the gas station is a big hassle so you are used to always filling up from empty. With the EV, my house is my refill station, so I just connect the cord every time I park. Even after a long trip where the car is near empty, charging slowly for 2 hours is enough for a quick errand. I’ll admit that I would have some charging anxiety if I only had the EV with no backup, but practically speaking it just doesn’t become an issue. Just keep enough charge to make it to the nearest hospital, and get a level 2 charger (240v/>=32amp) for almost 4x the charging rate.
