The second line stopped me in my tracks, "on the proverbial chalkboard," what's so arresting about such a line, I hear the other readers ask. Why, it's a metaphor within a metaphor. It's so weird when a poem uses terms such as "figuratively" or "proverbial," I mean, if you wrote "a mark on the chalkboard," it's already be proverbial.
Except poems also paint pictures, so we need to know the narrator is doing this internally, that they mean it as a proverbial, because the narrator and poet are not necessarily one. At least when it comes to imagery.

I'd definitely cut the apostrophes around "inspiring," do you really need to point out that you're using it ironically, in this piece? And if you do, for certain readers, will the piece reach them anyway?

"Erasure susurrus" is a joy of an alliteration, the "A burst of light" stanza was great.

"Buckets free of fluid" is a good metaphor for things without purpose, but "free of fluid" rather than "empty buckets," meaning that escaping our intended role, our intended use is freedom. There's a song in Hebrew where the most important line is, "Because to be free is to be completely alone." You have to accept giving up your role, your position, for freedom. You have to accept a self-appointed uselessness.

Free of fear
or
free of people.

Same idea. This isn't an "or" that means "Either this or that," but rather, "X, or in other words..." And it's important to note much of the piece really is made up of these, not of alternatives.

I find the use of non-sequitur follow-ups to be interested. It's most striking in the "Erasure susurrus" stanza, but I do feel you've over-used the feature in some places, and that you should've made clearer some of the mini-messages. The bigger message is clear, because it was actually not using non-sequiturs, about the folly of listening to those who claim to know, about empty platitudes. So you tied empty platitudes and made the continuation almost zen koan-esque, to show us what nonsense it is.

And that is how the "not of alternatives" makes sense. Each of those two statements means just as much, or nothing at all.

But there are limits to that.

I did like how you called out the prodigal son is an asshole.
Or, how the plainclothes prophet is.

What is this piece, in the end? An ode to mortality, to how we leave nothing behind. To how we lie forgotten.
