Yea, this is the crux. Using a particular tag in your post is a prediction that people who appreciate the content clustered around that tag will like your post. A good portion of the time that is based on accuracy, but sometimes it isn't, as I already explained (especially in the most used tags). Instagram was never set up to have the specificity of a search engine.
I agree tags are less useful now, because the feedback loop is broken after Facebook's changes, but it wasn't always like this. Every point I've made is about a particular period in time, not the present.
