I think the biggest obstacle to getting very far with technology-from-scratch, even with good garbage scavenging, is that just staying alive takes really rather a lot of effort. Of course if you're alive now and you have advanced technology to make the just staying alive bit easier, you could get really quite a lot done in terms of technology from scratch.
Exactly right. Civilisation wasn't able to really advance until we had food surplus and ways to store food. I've often thought that 'social society' for want of a better term would be very necessesary, post collapse. That is to say a way to divide labour duties; "George, you are good with finding food, you go with Edna and bring some back. Edith and I will stay here and build fire, and work on making knives."
I would be very interested to see a 'tech tree' going from Stone age to Laser.
