There are lots of people who can't easily have an electric car, they
include my parents who live in a street of Victorian terraces with
narrow pavement. However I think more than half the population could
charge at home.

So what do the other half do..?

Something else. There doesn't need to be one solution for everyone.

but the solution isn't in the hands of individual - I can't just decide
to have a charge point connected to the local street lamppost

No-one can because the street lights are on circuits not much bigger
than a 13A ring main, Separate from the supply to premises. Unless the
premises supply is on overhead wires (typically rural areas), when
there's a whole other set of constraints in the overall amperage.

HMG has to facilitate it (even if they don't directly provide it)

County Councils provide the street lighting.

The future for other than residential trickle charging top-ups is likely to
be fast chargers at filling stations. They will, of course, need a high
power grid connection, but that's simpler than rewiring the entire local
electricity supply grid, or setting up a whole hydrogen supply chain.

The new Taycan (and, no, Roland, it's not aimed at you) represents the
current state of the art:
