Answer:
Because the individual may have a different path than the many
Explanation:
By limiting to the "healthy standards of development" so to say, the love relationships will be heterosexual, intended for the biological reasons of bringing a child- this means other styles of life like being single, having a vote on chastity or being homosexual and having no offspring will not be included.
This why in many circumstances an individual path will go wide astray from the many, and perhaps will that person benefit the most, from it. <em>It may happen that is also a lifestyle that is not imposed socially.</em>
Another of the strong arguments against Erikson model is that persons will keep searching identity well beyond the adolescence, into adulthood.
