I'm in Spain and while everything you said is true it doesn't solve any of the issues I've listed, it just makes them less likely because:
- there are plenty of places were there is no another fast charger nearby. You can't plan on reaching a charger with less than 50km if range because if it doesn't work you may be fucked. that adds to range anxiety
- there are some networks that support NFC cards but majority doesn't. Using NFC card is usually more expensive as it goes through a different operator
- yes, you can wait but it fuck up your schedule and sitting in a car for 30 minutes is not fun
- yes, if the charger is completely offline it will not show. More often they are malfunctioning but still showing as active
