There is no way to reference a specific quote on Wikiquote.

Why and when would anyone want to "reference a specific quote on Wikiquote"? Use case welcome.
You can provide a permanent link to any revision of a page or a section. If you want to reference (in a scientific sense) a specific quote then you'd need to reference the original source of that quote, and the original source is never Wikiquote.

If you need to reference anything, it should be the primary source, not WikiQuote

Let's say I want to share this quote with someone:

I am a slow walker, but I never walk back.

I could... copy the whole quote, which loses where it came from, and also the citation of where it originally appeared. Or I could just send you a URL to the quote and you will get the source (wikiquote) the full text of the quote as well as the full citation.

This is exactly like how on Phabricator you can link to a specific comment, or on Facebook you can link to a specific post, or on Twitter you can link to a specific tweet.

I honestly do not see the utility of Wikiquote without this feature.

Of course, but that doesn't stop people from linking to Wikipedia pages.

That's what sections are about. So you seem to ask Wikiquote to make every <li> element a section.
I don't know of a website that provides IDs to link to the x'th item in a list by default...

I'm saying the content model might need to change.

Wikiquote is a free online compendium of sourced quotations from notable people and creative works in every language, translations of non-English quotes, and links to Wikipedia for further information.

https://en.wikiquote.org/wiki/Main_Page

If the primary content is "sourced quotations" then that's what we are storing / retrieving. Each sourced quotation should have an id and be indexed and linkable.

Right now, the content model is:
Notable Person / Work → Section → Sourced Quotation
and yeah, in that model, why would something two levels down have an id?

But, as per the description of the site, the content model should be:
Sourced Quotation → Notable Person / Work
In this way, a Notable Person / Work is more of an "author" than an object.

A way to express this is kind of like twitter:

Here's a link to all of Obama's (the author's) quotes;
https://twitter.com/BarackObama
and here's a link to a specific quote:
https://twitter.com/BarackObama/status/964185606803853314

Wikiquote, I think, should work more like this, and less like Wikipedia.

The purple-numbers idea is about adding anchors to every paragraph or list-item (etc.) as little purple-coloured hashes or pilcrows at the end of the block. I don't suppose it would ever be considered on a Wikimedia wiki as it's often considered a bit annoying to readers, and anyway seems to have died out in recent years.

Apologies for responding to such an old comment but I’d like to share my thoughts. I see this proposed feature as being functionally similar to anchor templates on Wikipedia, which seem to be specifically designed to allow someone to link to a point in an article which is not distinguished by traditional sections. However, in the case of Wikiquote, this functionality may be even more valuable (you more commonly want to share a quote with someone than you do a list of quotes from them). I understand if commenters had in mind its usability for interwiki editing, research and the like, but I see it as valuable in the sense that it makes Wikimedia projects more usable as an open source of online information.

People who want to share a quote they specifically found on Wikiquote are more likely to copy and paste or screenshot than they are to locate the original sources that the entry uses. And I think we can all agree that allowing for one to link to any point of a page, with its references and revision history accessible, is a great “compromise” to that situation. I have the same argument for Wikipedia, and it’s why I like anchor links. This is not to say I think implementing this on Wikiquote will be easy, but I think it is a good start for each quote to be considered a separate entity.
