Arguably, since “anything” is only used in negative sentences, it is kind of part of the negative. You wouldn’t say “I have anything”, only “I don’t have anything”. Then again, it can be used in positive sentences like “I would do anything” with a slightly different meaning.
But let’s take “anymore”. “I can’t stand it anymore” is a common phrase but “I can stand it anymore” not so much. “anymore” is only used in negative sentences so the “not” is arguably redundant and therefore “not … anymore” is kind of a double negative.
And even that’s not true for all speakers of English. There are native speakers who would say “I go to town anymore” unironically.
Edit: I reread the comment you reacted to and to say it’s “to emphasize” is wrong. That argument would work better for “at all” for example. My point is that “double negative” isn’t as clear cut as it might seem to be at first glance. “I don’t know nothing” is a double negative for sure, “I don’t know anything at all” kind of in a way, “I don’t know anything” maybe a little bit.
First of all, something like “I’ll have anything” is a valid and reasonable statement that is not negative, for example when somebody asks you what you want to drink.
But further, “anything”, “anymore” and “at all” are all very different - from what I understand, “anymore” doesn’t even exist as a word in British English, and I’d point out an example of “do you have any more?” as another non-negative. I think generally “anything” makes more sense by itself than “anymore”/“any more”, and “at all” similarly needs context. But just to provide a not-really-negative example, “Do you like it at all?”, where a positive response (“yes”/“I do”) does mean liking something.
In the end, I think your arguments might be stemming from trying to apply the term to too many things, from my understanding double negatives are very simple in that they need to have two negatives. A word being general, and used mostly in negative statements doesn’t mean it’s a negative, and that the actual negative part of the sentence is redundant.

This is close to the dumbest thing I read today, though to be fair I haven’t been reading that much today.
