There are many ways to add value, and one of them is to just identify and categorize a bunch of ways to add value!
People don’t automatically know where the treasure is. Sure, there’s value in digging up the gold, value in shipping it, value in refining it, value in smelting and smithing it, and value in selling it. But there’s also value in just figuring out where to do all that stuff!
If you’re confused about how to add value in a given situation, probably so are a lot of other people. That means you already have the answer: you can add value by identifying other ways to add value, and sharing that information. You can add value by making the treasure map.
