All EV's (excluding "quad bike" such as Ami and that Renault thingy), from every spectrum, have the capability to rapid charge using the single plug standard in Europe known as CCS.
Nissan Leaf and a few other early Nissan only support Chademo rapid charging. This is an Japanese standard that is not mandated by EU.
Early Zoe only support 22 kW AC charging, still fast enough for its battery if you can find 22 kW charge points. Last few years, Zoe 50 have CCS rapid charging.
A comparable car to the Golf would be MG4, starting from £27k (Golf starts from £26.5k for a manual). This have CCS rapid charging as well as LFP battery giving around 200 miles of range.
The statement is correct for vast majority of cars being produced because vast majority of cars are being used. You are using an extreme use case just for argument sake.
The National Grid ESO (second link in my earlier post) is not a power company. They don't sell energy. They are responsible for ensure smooth operation of the electrical grid.

The Dacia Spring is rumoured to be "well under £20k", will be on sale next year: https://www.autocar.co.uk/car-news/new-cars/dacia-spring-city-ev-finally-confirmed-uk-sales-2024
Corsa petrol starts from £19k.
From purely vehicle powertrain point of view, this is true.
But BEV are more than a car, batteries are the new frontier (to quote an old thread title).
Battery can provide more electrical power than a running engine can provide, this is useful for many things other than moving a vehicle.
Battery can also store excess renewable by charging slowly on command. Battery can even be used to support and balance the grid using V2G.
