You have to think much harder about the macroscopic scale. Things on a macroscopic scale don't work quite the same was as they do with subatomic particles. Oh sure, you can apply the same types of formulae, but the results are strikingly different which you don't seem to appreciate at all.

Would I see an old friend at the store? Which cars would pass while I waited to cross the street or which workers would be at the store today.
These things are in a state of superposition until I walk to the store. There all probable paths. When I walk to the store it then becomes a measured event. I then thought that quantum information and the Observers mind must be connected.
So, when you talk about getting a baseball through a slit that's roughly a billionth of a trillionth of a trillionth of a meter wide, how are you going to do that? It sounds pretty silly to me.
Diffracting sound waves is almost trivial, but for light
waves we need one or more extremely narrow slits (gratings with spacing of the order
of 10^-6 m). For X-rays and electrons the grating pattern has to be finer still (of the
order 10^-10 m as found in crystals). Now, what about the diffraction of a “beam”
of baseballs? Using the de Broglie formula, for a nominal baseball momentum, one
computes slit widths needed to diffract such a beam to be of the order of 10^-34 m!
The impossibility of such a grating is given as the reason why baseballs are not seen to
diffract.
However, a closer look at such reasoning shows serious flaws. If slit widths of the
order of 10^-34 m were actually possible, there is still no way one can imagine baseballs
getting through them (baseballs are simply too big!). The transition from an electron
to a baseball is not merely a change in mass. An electron is a structureless fundamental
particle whereas a baseball is a composite of an enormous number of fundamental
particles bound together. This means that an electron has no measure of spatial extent
or size but the baseball has a well defined measure of size based on equilibrium distances
between component particles. For the baseball to squeeze through a narrow slit, the
distances between its component particles must be decreased dramatically. This would
require ridiculously high energies.

This is an interesting theory. I've never heard it put this way before.
However, I don't agree with you.
Example.
One person is walking down a unknown path. They see a tree.
Another person walks down the same path and sees the same tree.
If the tree does not exist until it is observed, then how do two separate minds create the same tree?
The problem with applying quantum physics on an macro scale is that quantum physics / mechanics specifically deals with the micro.

I know a baby grows inside a pregnant woman even though I can't observe or measure it.
But you either read, saw a photo, saw on TV, or heard about them (all perceptions) and believed it.
I gave you a challenge to prove this by shooting a stream of baseballs through diffraction slits to demonstrate that they aren't on a macro scale and will exhibit quantum behavior.

Yes, a baseball is indeed a macroscopic object.
Macroscopic objects like baseballs have a very large number of degrees of freedom due to
their large number of component particles.
I understand some of that paper may be over your head, but that part certainly shouldn't be. And I think it refutes your claim that no macro scale exists. I don't see you accounting for the fact that "This composite nature of macroscopic objects gives them properties qualitatively different from microscopic ones."
For the purpose of quantum mechanical analysis of observation, macroscopic objects
like baseballs cannot be treated as just scaled up versions of microscopic objects.
Macroscopic objects are made of a large number of microscopic objects tied together
by some forces. This composite nature of macroscopic objects gives them properties
qualitatively different from microscopic ones. The quantum description of composite
objects is in principle straightforward but computationally time consuming.
