Intuitively, I agree. This feels like the different between being a creator (of your own thoughts as inspired by another person's) and a consumer (although in a somewhat educational sense). There would need to be a big advantage to being taught those initial thoughts, analogous to why we teach folks algebra/calculus via formulas rather than having every student figure out proofs for themselves.
