You seem to be happy that someone can protect a single 40W light bulb

thought - far enough...

But that is exactly what happens with unfused plugs. And unless you are
going to return to the days of 5A and 15A sockets (and a plethora of
adapters, often unfused) *all* the socket circuit MBCs have to be
adequate for the heaviest load eg 3kW heater so the circuit cannot be
protected at a lower value. This is exactly what happens in countries
with unfused plugs - table lamps on 16A or 20A circuits.
