In this context, putting a normal link on the image is the most usable
way of providing a long description. How can aria-describedat be made
as easy and intuitive to use as a normal link?

The advantage of using aria-describedby as an enhancement *where
required* is it still "works" in UAs that don't support ARIA, and for
users that don't know to use ARIA, and when authors use ARIA
incorrectly. As I understand it, aria-describedby was specifically
designed to point to element(s) on the page to avoid repeating the
same mistakes that made longdesc a disaster:
