I can relate to losing fundamentals such as this. I could not remember for years why music or anything man-made really is such a hype in society that they constantly talk about it even visit places just to see what previous generations had made.

To answer your question:
Because your locality can't produce and maintain the knowledge needed to run civilisation in your neck of the woods. Let alone the goods necessary to run our tech civilisation, like glass testing vials, toilet paper, noodles, machines that make noodles, computers that make computers, mining and transport machinery for raw materials and food.
Not only does your area not have all the required raw materials, it also doesn't have the manpower needed to staff the education centres and factories.

Downgrading into a far less complex civilisation that works on resources in constrained areas like the state of North Carolina, Nigeria or Norway, like in the pre-industrial era, is nigh-impossible without unconscionable suffering.
And the knowledge relevant for such a new-old life organisation has vanished out of memory 3 to 4 generations ago in industrialised countries.
