You really, really aren't. Still, let's go back to the beginning of this and take a look at what's actually been happening.
A suitable analogy would be bringing up the
Observer effect. The original statement in question was, in short, just like saying that it is impossible to know both the exact location and velocity of an electron at the same time, with the exact why left unstated because it really didn't need to be stated. Namely, it was about what we can know/do. 'We' of course, referring to all observers bound by reality's rules. Your response, in comparison, could be taken in two ways. The first was like saying that 'if the electron doesn't have a position and velocity, it doesn't exist.' In other words, you would be stating a
trivial and entirely irrelevant truth. Of course the electron has a position and velocity and that was never in question in the first place, just like of course a thing that exists is detectable and demonstrable, if you ignore everything that would prevent such from being doable.

Now, with that said, demonstrable is still not part of the requirements for existing, even at the
trivial truth level. Existing is certainly part of the requirements for something being demonstrable, though. This goes back to the objection I had with distinct, but not distinguishable. Demonstrable and distinguishable are fundamentally actions. If there's some reason rooted in how reality works that they cannot actually be done other than that whatever it is doesn't exist, and conceptually, there certainly are reasons that would suffice, then they can't be done, but the thing in question could still exist. This is opposed to distinct, which, like existence, refers to a state of being, rather than an action.
This would point to the first of the two, then.
If not, you've merely been fighting an entirely
irrelevant battle.
Nope. Your version of theoretical is
irrelevant to what was being said in the first place, by the look of it, though.
Heh. No. It really is all about practical results and ways that can help get practical results, when you get down to what's actually happening. That's really what distinguishes it. "A meaningful definition of the word 'real'" is nothing more than a convenient and entirely superfluous bit of philosophy that some people try to add.
Only if you're including magic that breaks reality, which cannot exist, even in principle, which renders your argument worthless from the start on the topic in question.
And the question was about whether it could be known to be true or false, not which one it actually is.
Except that nothing you put actually made it an invalid statement internally. The closest you came was claiming that it was undetectable. The place to go from there is "Why is it undetectable?" If the answer to that was stated, maybe it could be shown to be invalid, depending on the answer, but not necessarily. You did not state such, though, therefore X exists is not an invalid statement, as it was made.
