a correctly sized plug top fuse protects from fires being caused if the flexible cable is damaged and short circuited as it will open long before the circuit breaker in the distribution board does (which could be 15 or 20A in USA)
The UK has them because we use an unusual ring final circuit which generally has a 32A circuit breaker; so a short circuited cable could get *very* hot without the plug top fuses
