I could be wrong, but I understood this to be a way of getting yourself in the door. Bonds created by the "indebtedness" are I think starting points to spending time with people and getting to know them, rather than a friendship in and of themselves.

It might be a starting point but it doesn't provide the fundamentals to get you where you want to go.

This reminds me of what pickup artists teach. They teach tactics for how to get in the door, and forget about the fundamentals of actually building a real relationship.
