Non-substitutability

Non-substitutability refers to a situation where a resource, good, or skill cannot be easily replaced by another. For example, certain unique talents or rare materials are irreplaceable because no alternative can perform the same function or provide the same value. This concept highlights the importance of specific, one-of-a-kind assets or qualities that are essential and cannot simply be swapped out without losing their original benefit or significance. It emphasizes uniqueness and the inability to find substitutes that match the original's function or value.
