Some things really are primitive notions. And for each primitive notion there will be *someone* who will deny its existence. Your claim seems to be that if I argue against them claiming that it actually does exist then I concede that it’s not a primitive. That doesn’t seem like a very good argument.
One could certainly debate the existence of say points, without disputing that they are a primitive notion. For instance, one could argue that points are a contradictory concept since they have an area of zero, but that each point that we can physically draw always has some area. Someone could then present a counterargument to that. Neither of those arguments would dispute points being a primitive notion.
Rather my argument is that if you are discussing the existence of a primitive notion, you have to explain what it would mean for it to not exist. Otherwise it is hard to understand what the debate is about, since naively, points/qualia seem to self-evidently exist.
You said “That wasn’t what I meant”—and yet you wrote “if people don’t know what you mean from an example, then it doesn’t seem to work as a primitive notion” and “to discuss the existence of points as something which is up to debate, seems to already presuppose that they are not a primitive notion” and “otherwise there would be no need to argue for the existence of points, nor could their existence to be disputed”. So I don’t know how that could possibly not be what you meant?
Anyway, dealing with your argument in this comment, someone could claim points aren’t primitive because they are the intersection of lines and someone else could claim lines aren’t primitive as they are made up of points. According to your reasoning, neither can be primitive by mere fact of disputation. That doesn’t seem very convincing.
“Rather my argument is that if you are discussing the existence of a primitive notion, you have to explain what it would mean for it to not exist”—So what does it mean for a point not to exist? What would it mean for matter not to exist or logic not to exist.
