Having to hunt for traders to actually craft things is bad game design. Ancient Stones can be found in the nether and are common enough that you don’t need to trade for them anyways.
Things with bragging rights I always see as stupid, as everyone should be able to find things easily, even if they have too search for awhile. So, while I still believe in treasure items (Items that have no use but can be displayed), having them to be “Bragging right” items is not the right way to go.
