The quote from Larry McMurtry's "Lonesome Dove" reflects the notion that, similar to humans, some plants may offer little value or purpose. This comparison suggests a broader theme of functionality versus futility in nature and life, highlighting that not everything has intrinsic worth. The sentiment explores the idea that, just as some individuals contribute meaningfully to their environments, others might not fulfill any significant role.

This perspective prompts readers to consider the diversity in both human character and the natural world. It raises questions about the criteria by which we judge usefulness and value, urging a deeper examination of our connections with both flora and fellow humans. Ultimately, McMurtry's insight serves as a poignant reminder of the complexities found in relationships, whether they are with people or the plants that surround us.
