I made no such argument regarding simplicity. Nevertheless: even if a solution turns out to be too difficult for users to understand no matter how you present it (at which point you might want to rethink whether this apparently fundamentally flawed idea should even be implemented at all), violating your users' agency by taking the reigns and obfuscating the whole thing to them is morally wrong and in simple terms: an arsehole move.
