It is of no value to the world in so far as it now barely exists outside of academia and people are no longer made to feel that they should engage with art culture as a necessary part of their self-education. Even if a person makes a conscious effort to explore beyond the high school favourites (Shakespeare, Blake, Dickinson...), they will probably only encounter tired collections of early-mid 20th century figures at the latest unless they become entangled in the hackwork of Rupi Kaurs that fill new releases shelves. Much contemporary poetry is written by professors and published in journals only read by other professors, and consequently is not only difficult to find but also drily pandering and uninteresting.
An individual can easily attune themselves to a poetic sensibility if they want to, but it takes more effort than a lot of other media, and online documentation is abysmal compared to other art forms. Education in form or context isn't nearly as important as a general interest in language, abstraction, and sentiment, and the single time when most people are exposed to poetry (high school) is a terrible one, as it's unreasonable to expect children to be invested in these qualities at that point of their lives.
Volumes are printed in small numbers and often out of print, sampling a writer's work can be very difficult, meaning potentially many purchases are required in order to read what intrigues you - this being just the acclimatising phase, as when you find subtypes that particularly appeal, you will be travelling even further from the affordable collections of the established names and deep into isolating territory of authors that are impossible to find discussion of online in any specific detail, and even when you do, they are only mentioned in context of whatever homework assignment some student is doing. This whole situation leads to it becoming a solitary exploration, which may be demotivating for some, but can be personally enjoyable and rewarding if you're looking for some me-time.
My favourite thing about the medium is that it does not make demands of your time. It's not like a novel which can require a lengthy sitting to gain value from, or other linear media such as theatre or film which benefit from being experienced unbroken. You can browse at will, disregard the order of printing by the editor, work from the middle to the front of the volume. You can skim read while noting down favourites to check back later, or spend a long time on a couple of pages. Like viewing a painting, the more time to spend, the more value you can glean, although unlike painting I find poetry to offer a more direct line of engagement as it is built from synonyms, allusions, and phrasings on a small-scale similar to our everyday conversation and scattered thoughts. You can copy a poem that you enjoy, dissect its lines, reshape it, and adapt it with a casualness that doesn't apply to visual art or prose, which require some skill to successfully parody.
This openness of the medium doesn't override its core inaccessibility which is a lack of interest or perceived value in abstract musings versus the prostate-tingling twists and turns of conventional drama. For the same reason that a person might have a Turner painting as a desktop wallpaper but be unable to look at his work in reproduction or person for more than a minute at a time without zoning out, poetry requires you to meet it on its terms, as it can't possibly hope to live up to expectations of other mediums serving charms that it does not seek to provide. It requires one to consciously make room for it and allow it to become of value to you rather than it beating you over the head with something you've always needed but never knew. No revelations or complex narratives to pick apart, just pleasing turns of phrase that worm into your imagination, appreciation of an individual collection is a subjective experience beyond other already abstract art forms. With a poem there can be a literal or alluded meaning or narrative, but it can often be secondary to every other element of its construction, leading to a personalised way of reading that further enhances the sense of the reading being an act of self-exploration rather than conventional entertainment (and enjoyable in being this way).
