You are correct, this argument only works if you have a specific epistemic framework and a subjective idealistic framework which might not coincide in most subjective idealist. I only wrote it down because I just so happened to have used this argument successfully against someone with this framework (and I also liked the visualization I made for it). I didn’t want to go into what “a given thing is real” means because it’s a giant can of philosophical worms and I try to keep my shortforms short. Needless to say that this argument works with some philosophical definitions of “real” but not others. So as I said, this argument is pretty weak in itself and can only be used in certain situation in conjunction with other arguments.
This goes without saying and I apologize if I gave the impression that people should use this argument and it’s visualization to persuade rather than to explain.

(I think making arguments clear is more meaningful than using them for persuasion.)
