Knowledge is a collection of many pieces of a puzzle. The piece that is precious to you (because it was the last one you needed to complete some imporant shape) may be useless to those who already have it (btw it does not mean they have that shape already completed, they may be missing a different piece) or those who are missing the entire context so there is nowhere to connect this piece to.
A part of the problem is long inferential distances, which in theory could be overcome by a sufficiently large book (that you don’t have time to write, and the recipient has no time or motivation to read), but for example in your example 4 an additional problem is that the other pieces are not even verbal.
