"depersonalization" and "walls" is one way to put it. Though think of it from another perspective: You'd need to keep a team pulling in the same direction and speak a common language. When one person coded up something without any framework, they may understand the code structure perfectly, but the others who collaborate with them can easily get lost/be detoured. Publicly existing frameworks have conventions, docs and communities and a certain way of organizing things, which makes it much easier for a team to avoid wasted efforts.
