your opinion is born out of ignorance.

Many vision impaired users of AT are not totally blind, they can have
varying levels of vision, therefore they may well know there is an
image there, but not be able to identify it or have a guess that that
blob they see is an image or can sort of guess what the image depicts,
but the explicitly associated content helps them to positively
identify the image or make sense of the blobs or blurs. if content is
not explicitly associated it can be very difficult for vision impaired
users to correctly identify what goes with what.
