Is there any other project that has tried to start from the beginning for research or education propose? It would be interesting to see in a congress or seminar a project demonstrating how it all started in real time.
It is unbelievable how Satoshi has worked so much almost alone. If he is just a person and not a team. There were some other ideas in the beginning as building a poker game and a marketplace. But he has gives up.

Theymos has explained why Satoshi didn't continue with the idea of "people to do all economic activity through the Bitcoin client"
The client was supposed to support auctions, reputation, etc. But Satoshi didn't have a very good design for any of this. For example, his solution for preventing spam and ensuring that scammers couldn't immediately create new accounts was apparently for every user to solve some Bitcoin blocks, which today sounds totally nonsensical -- no one mines blocks solo anymore. I think that he realized the design issues, abandoned all of this, and added the RPC interface so that websites could do this stuff instead.
