The throughput of a charger is a lot lot lower. A single pump can maybe serve 20 cars an hour if it’s got a credit card reader. Most petrol stations in the UK have this and maybe 4-12 pumps depending on size. So just ball parking, if the average needed duration to charge is 10 mins on a supercharger, you need 4x more chargers than you would pumps for an equivalent.

The obvious difference is that you can’t pump your car at home, and by installing chargers in ordinary car parks you can mitigate the need the specific infrastructure of petrol stations, but the number of total chargers needed is still high, they are just not in the same places.
