In which messages did you acknowledge that it was an abstraction?
This was my question also. The only way I could make sense of it was that she has actually been setting up the 'geological column' as a strawman to be refuted at some point because it is so inconsistent. But that's still a reach.
That is kinda the route she was going in the other thread. Take a look at the exchange starting at Message 1229:
No one will agree with you because you just like your own definitions better than the ones everyone else is using and agrees upon. I'm sure everyone would be glad to switch to your definitions if they made any sense, but they don't. Wherever you might stand upon the surface of this Earth, you are standing atop a geological column. No location is an exception, and the specifics of the strata underlying any location matter not. Sediment can add to any local geologic column anywhere, regardless whether that column includes deformed or eroded stata.
Then the whole idea of the Geologic Time Scale, which was built on the idea of a vertical stack of horizontal layers that are found here and there in various proportions, is false. If you don't have an ascending vertical structure, a column, you do not have a time scale represented by the rocks, which could only be physically represented by such an ascending vertical structure.
I think you are all mad as hatters.

No, not just here and there. Its everywhere. Every single point on the surface of the Earth has layers below it. Those layers below it are called the "geological column" for that particular section of the surface.
Each section will have its own column. Some sections are bigger than others.
I'll have to look it up but the layers aren't everywhere on the earth.
Yes, they are. Everywhere.
There is no place on the surface of the Earth that does not have underlying layers. That's impossible. What would the surface be sitting on?
A Column is a VERTICAL Structure
The Geological Column isn't like a real actual "thing". Its an abstract.
It is a cross-section of what layers are underneath the ground at some particular place. Different places are going to have different columns.
If you took a giant metal tube, forced it into the ground, and then pulled out a big stack of the layers underneath, then you would have a column of the underlying geology. You could then study each layer to determine the properties of the past. Here's an example:
