Not all things can be independently crafted, but in some cases, yes, there's a fourth option: create for yourself, independently, what they have.

That's a tall order for most items, though. You're going to have to ask someone for things.

Hidden within "asking nicely" is all sorts of stuff like mutually beneficial reciprocal trades--it you stare at it from the right angle it clearly is a form of "asking nicely", though the nice ask is coupled with substantive actions.
