I agree with you. I charge at home weekly. I expect to have enough solar soon that I'll charge whenever the car is at home and the sun is up

When doing long (2 days of driving) trips I haven't had any trouble getting a charge. High speed DC chargers had few queues (I had to wait 5 minutes once) and motels have usually given me parking near a power point. I'm in Australia so over night gives me 8 hrs * 240V * 10A = 19.2kWh which is usually enough to get to the next fast charger

Swappable batteries might be nice but I doubt they'd be profitable (with home charging) with most just using it to swap end of life batteries for better ones

They'd be ok for people living in apartments or otherwise with no charging at home, but better would be charging in carparks at work
