question about releasing increments

Question from the open assessment:
It is important that the product increment be released to production or shipped to customers at the end of each Sprint?
correct answer according to scrum.org: no

I don't agree here. I know that it is not mandatory for Scrum to release each increment, but if it is not 'important' than why did you build it? Increments should be of value to the customer/business, and they have no value as long as they are not released to production.

The question, imho, should be:
It is mandatory that the product increment be released to production or shipped to customers at the end of each Sprint?

or

It is important for the Scrum proces that the product increment be released to production or shipped to customers at the end of each Sprint
