It points out that any given suffix removed from a chunk's linearization, provided it leaves at least one transaction behind, inherently possesses a higher feerate than the original chunk. This phenomenon occurs because if the resulting chunk (after the suffix is removed) had a higher feerate, it would have been selected as the chunk in the first place.

This insight underlines the importance of transaction selection and organization within systems, emphasizing how feerates influence the structuring of transactions. It suggests an inherent optimization process in the selection of transactions for inclusion in a chunk, where the system naturally gravitates towards configurations that maximize the feerate. Essentially, this observation sheds light on the dynamics of transaction fees and their impact on transaction organization, offering a nuanced understanding of how transactions are prioritized and arranged based on their feerates.
