1: You're forgetting that the market board allows you to buy raw materials.
2: If you max the rank for each of the 6 zones of the expansion (As you'll probably do while farming bicolor gemstones) you'll unlock the ability to buy Every Monster Drop for that expansion in both the major and minor city's bicolor vendors. Remembering the expansion that an item is from is considerably easier than remembering 6 vendors' locations.
3: Doing FATEs is faster than farming monsters for ShB/EW/DT materials, and the price of SB raw materials is absurdly low due to uneven supply and demand as a result of people running Gazelleskin maps a lot more than any other Timeworn Map.
