Why are names important?

One Opinion:

Your name is very important! It identifies who you are, and if you don't have one, it's like you don't exist. You sign your name on your checks, you give your name when greeting people you don't know, you label your property with your name, and people won't know what to call you. It would be funny if somebody you knew said "Hey, Person, look at this!". Personally, I think that "person" is very generic for a description of someone.

Another Opinion:

A name is a quality with utility.

As a quality, it identifies who you are, and if you don't have one, others may find it more challenging to refer to you, and the ability to refer to and identify a subject is integral to complex communication. In English, it'd be naturally troubling to explain to someone that you wanted a chair if the Word "chair" was nonexistent.

It has utility in that, you use it to sign it on your checks, greet others, and label your property. A unique name, such as "John", accomplishes these things by helping separate you from the rest, while a general name, such as "person", does not.

A name is not important in that it is a necessary quality to have, however it may be an important factor to include when it becomes, quite literally, the subject in language.
