You haven't made a single compelling argument as to why we cannot also rebuild social infrastructure.
Much of this social capital requires lots of folks being interested in something since they were young and "playing" at it. Play is an important way to learn and understand it. Also I believe social capital requires adults to respect and take interest in the item, as children often take their cues from that.
That said, I wonder if industrial clothing manufacturing requires that much social infrastructure? That industry seems to move very couple of decades to a new country with the cheapest labor.
...and I don't have to.
Have a nice Easter/Passover!
For our own sanity we have to believe we have at least some handle on the reality unfolding around us - but even a cursory examination shows this cannot be true. Our lives are so brief, so localised, when set against the totality of all that is, was, and will be. Instead, as we shape the world, the world shapes us, and it is this emergent collective consciousness that conspires to give us all that we have.
Basically, it's the social structure that is built around a community's Raison D'etre, or reason for existence.
This is schools, housing, curriculum (there's a reason that RIT is based in Rochester, for example), as well as oral and learned tradition.
"Tribal knowledge" is a dirty word to efficiency nerds, but that doesn't change the fact that it exists, and is highly effective, for a reason.
There are entire districts, known for the finest $WHATEVER. Lübeck, Germany, is known for marzipan (I don't really like it, but lots of others do). Bordeaux is known for wines and cooking, Afghanistan has some of the best opium, etc. Some of these are due to climate and soil, but others can be lost to other areas (Sonoma, for instance).
They may have great soil, but they also have great farmers, who have been handing their skills down, for generations, etc.
Once that is gone, there ain't no making new ones.
