The claim that goodwill is the only asset which competition cannot undersell or destroy is partly realistic, yet ultimately it is exaggerated. In my view, goodwill, which we define as reputation, trust, and lasting stakeholder relationships, differs from physical capital because this asset is socially embedded and hard for competition to copy. Although I agree that such goodwill cannot be directly undersold, I disagree that this reputation and trust can never be damaged or destroyed by competition.

Clearly, strong goodwill generates a resilience that rivals in the same competition struggle to replicate. Prices and networks can be imitated, but the trust and reputation built through consistent quality and genuine integrity develop only gradually, and this makes goodwill a durable asset. For instance, a firm whose brand is recognised for dependable service often retains its value even when competition offers a lower price. Therefore, such loyalty demonstrates why goodwill and reputation function as a lasting asset that competition cannot easily undersell.

However, goodwill is not indestructible, and even a trusted brand may lose its reputation. Indeed, the value of goodwill can deteriorate because of internal failures, such as poor integrity, data misuse, or a damaged name and lost credibility. Moreover, competition may weaken goodwill indirectly, since when innovative firms raise standards, an older brand can seem outdated and its reputation and esteem may diminish without any price competition.

In conclusion, goodwill is uniquely resistant to direct competition because this asset is relational rather than transactional. Nevertheless, the reputation, trust, and credibility behind goodwill remain vulnerable to mismanagement, so the claim about this asset is realistic in emphasis but unrealistic in its absolute certainty.
