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.
