I'm in agreement with you. Another way to think of it is, why would you put a table of contents in a 1 page "book"?
Sql Server will ultimately pull the whole table in memory since it's so small, any indexes or PK's will just add overhead. However, the unique index would probably be a good idea to retain data integrity.
