A "meta-argument" against all future arguments for God's existence ?

[The Grand Nudger]

Names, designs, emotions, music, literature, and painting are all very efficacious- and also very material.

Perhaps, they appear to be material bc we only encounter a material form of them:

All those things are information. Maybe in the case of emotion, some people would call it a brain state or emotional state.

Not just emotion, but any and every thought yeah.  

For a name, you might see it printed on a door or on a newspaper or on a website.
You can have the exact same name “George” appear on a door, in a newspaper, on a website.
You can’t have the exact same atom located in multiple places at the same time.

And you can have the same exact car in multiple places at the same time, but that doesn't lead us to posit that cars aren't material.  

When the name “George” appears on a door, it is a structure. It is a specific arrangement of smaller components: molecule/atoms.
It is just paint and plastic.
It takes a brain to understand the structure.
You can even take the paint and plastic and change its structure and have it represent a screwdriver.

Screwdrivers, notoriously material.  

When you go to your hardware store and are interested in a certain drill. You might find boxes of the same drill. They are all the same design.
Design is information and information can be copied and destroyed.
The atoms/molecules of drill 1 and 2 are not the same but the design of drill 1 and 2 is the same.

Hope that helps.

It's a running description of material objects and material interactions.  If material forms are the only thing I encounter - then even if we lived in a world bursting with immaterial whatsists, it would be irrational of me to believe as much.  Most of the time, theology invokes a veil to explain the disconnect - tacit acknowledgement that the immaterial is nowhere to be found - at least by us - at least here - at least now. It's also the basis of belief in ritual or magical objects. Totems that can help you to apprehend or interact with the other - because even when we're positing the immaterial.....we can't escape describing it as nominally immaterial. Monkeybrains.
