Settle down there, champ. This has only been done in a single expansion - Stormblood - which isn't even the most recent one. Before that, DoH job quests in Heavensward straight up required a master recipe to complete. Facet deliveries, the system that replaced DoL/DoH job quests in Shadowbringers went back to requiring actual materials. To complete those, CRP requires intermediates from WVR and LTW. BSM needs lumber and yarn from CRP and WVR. And Studium deliveries, the Endwalker iteration of the system, is largely the same.

DoH jobs are designed to be interconnected through intermediates. It makes them dependent on each other. And yes, that means that you are either accepting that this is an "all or nothing" system where you level every job, or paying the MB prices to fill the gaps in what you can do. This applies to any crafting as well. You aren't making most of the new crafts without every DoH leveled, or buying intermediates. So your initial idea to make gil with only one crafter was futile to begin with.
