If I had a perfect understanding of both technology and the problem domain, I wouldn't need feedback. Yet, usually we find ourselves in a different situation of less than perfect understanding of both, so we seek feedback to avoid going in a wrong direction. The less understanding, the more of it we seek. But there has to be a logical limit to that, otherwise we could come to a conclusion that things could be accomplished by someone with nearly no expertise, given enough feedback.

The secret lies in the fact that neither giving, nor receiving feedback is free.
