Upset?? when one is so ignorant; this has no room in a philosophical discussion; members who are easily upset often go into a rage [explicitly or subliminally] and do crazy offensive things. This is why I put those 'upset' in 'ignore'.
Let's even give a concrete example: I put the following in a room in a field. A stuffed horse, a computer, a set of big fluffy red dice, two chairs, a large painting on the wall of a dog staring with big eyes, and a bed in the room.
Why will 100 non-mentally ill Westerns make the same list of things?
I have already given the fundamental reasons why the 100 people will produce the same list of things, i.e.
When humans with the same psychological states enter into a room with things, they will get the same lists of the kind of objects.
Why?
Because
human nature is universal, e.g.
similar brain structures and set up, there will be similarities but not 100% similarities [e.g. due to different psychological states] in the realization of object-X.

That their human nature is universal, same brain structures, same pattern recognition faculty, same cognitive set up, same realization processes, same linguistic faculties are critical to why they will produce a list with the same name to those things in the room.
It is the same inherent human nature [biological and psychological] that all the 100 men shared that they produce the same listing.
Bats or other non-humans would produce a different lists [assuming they can list things].
I did not use the term 'quantum foam' rather I had used a 'soup of particles and quarks' in the metaphorical sense.
Here is the confusions from the rigid dogmatic hardcore philosophical realists;
There are many types of realists and many types of anti-realists.
Also an anti-realist can also be a realist in certain context.
A Kantian anti-realist is also an empirical realist.
However, ultimately, empirical-realism is subsumed within Kantian-anti-realism.
Kant in CRP wrote:The Transcendental Idealist [anti-philosophical_realist] is, therefore, an Empirical Realist, and allows to Matter, as Appearance, a Reality which does not permit of being inferred, but is Immediately Perceived.

Note also;
Reality as conditioned within a human-based FSK comes in various perspectives, i.e.
1. Common Sense
2. Conventional Sense -e.g. Newtonian, Einsteinian
3. QM sense.
Thus for a Kantian, the common and conventional sense are realized within empirical-realism while in the QM sense, it is realized with the anti-philosophical_realism perspective.
In the case of the 100 non-mentally ill Westerns listing things in a room, that is done within the common and conventional sense not QM.
In this case, what is relevant to the Kantian would be empirical realism.
Thus what is listed can be empirically verified and justified as real within the science-FSK.
The p-realists will list the same things in the room, but the difference is the p-realist adopt their listing within the hardcore ideology of philosophical realism with absolute mind-independence.
On the other hand, the Kantians
empirical realists will list those things and recognize them as merely relatively mind-independent subject and subsumed within Transcendental Idealism [anti-PhilosophicalRealism].
Re "quantum soup" of particles and quarks, the p-realists will insist on the absolute mind-independent ideology while the anti-p-realist do not.
