Why do you think the system was introduced with 1, 2, 3, 5, 7, 10 and

And it failed miserably.
On the contrary it was much more effective than the prior system
Really? With the previous radial system, you had a fuse per socket. In
theory...
not correct
So a 5 amp socket would take the fuse out if overloaded.
if the socket was overloaded by a large margin for long enough yes. But often not if the appliance went into dangerous overload. Why? Sockets were in short supply and most homeowners chose plugs to fit whatever socket was there rather than what fuse the appliance required. Those that stuck to fitting the corect plug simply used an unfused adaptor. Result: a large percentage of appliances were not appropriately fused.
Missing or inadequate earthing probably killed more people though.
