I see your point but I think your suggestion would require a full rework (more work) to pull it off. ALSO some of the schematics are only required for housing. If we gave everyone access then there would be too much competition on the market for certain things in which case it would become a likely scenario people go lower then the materials themselves to craft it... so the less people can build them the better. I think that using the workshop for private use should be treated different then how you use them for FC use so yes... maybe the GC can be used for privately used workshops instead of the apartments. However I believe that when combining both (instead of making people walk) would increase the chances of people feeling satisfied.
