Well apart form the obvious reasons, like cars being buried in mud for days, cyclists, bikers and pedestrians being unable to use the roads except in warmest and driest weather, shock absorbers, suspension, tyres would all have much shorter useful lives, much worse visibility due to all the dust, more difficult and expensive to maintain the roads, virtually impossible to fit reflective studs or road markings.... Braking distances on dirt roads are much greater than on metalled/surfaced roads and handling is worse so either there'd be millions of extra road deaths every year or speed limits would need to be lowered to around 30 mph. It might work in very dry climates with little traffic, but for everywhere else it would be horrifically dangerous.
Even a dirt road must be maintained regularly, or it becomes an eroded and impassable trough. Any road that gets much in the way of traffic must be paved simply because it takes less to maintain a driveable surface.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
