Pure BS, as repeatedly explained.
Including by the simple graphic you seem to hate as it so clearly shows the problem with your model:
Is the W, weight?
It can be considered the weight and would be by any sane person. But for this diagram, to avoid your nonsense about weight magically not being real, it is whatever force is acting on the air in addition to the air around it, which is trying to move it towards Earth which explains the pressure gradient.
Without this W you have F=G and thus there is no pressure gradient.
You need an extra force, no matter how much you want to pretend you don't.
Gravity provides this force and explains why there is a pressure gradient in the atmosphere.
Your air does not.
Atmospheric stacking is very simply push against resistance equally in all directions.
That is the key part, EQUAL!
That means it is the same force pushing up as pushing down. There would be no gradient. There would be no preferred directionality. Either of those requires it to be unequal.
Take away the G and the W and simply replace with P (push) and R(resistance).
No, you would need 2 separate ones.
You can take away F and replace it with P1, then take away -F and replace it with R1.
Then you do the same with G, making it P2, and with -G making it R2.
The air above pushes down, and it resists it, pushing back. Likewise, it pushes down on the air below, and it resists it.
But again, without this W, this force is the same and there is no gradient.
This push and resistance only works to explain a constant pressure from the bottom to the top, just like we can create sideways, where there is a constant pressure from left to right.
Again, you need an extra force to make the gradient.
There is no air pressure from above keeping you or I on the earth.
Absolutely there is.
Until you can explain how the air magically defies the pressure which should push things upwards, there certainly is no air holding us to Earth.
Molecules/matter can never move freely around.
Everything requires a medium to move in, which means everything is against resistance to motion, always. No free movement, at all.
This is just your baseless claim you have no hope of justifying. Repeating the same lie wont make it true.
Again, the way things boil and things like SEMs show that is not the case at all.
