I'd like to congratulate you on writing a wall of text that gave off all the signals of being written by a conspiracy theorist or crank or someone off their meds, yet also such that when I bothered to read it, I found it to be completely level-headed. Nothing you claimed felt the least bit outrageous to me. I actually only read it because it looked like it was going to be deliciously unhinged ravings.
“The meaning of words and concepts is derived entirely from relationships between concepts” would be a pretty outrageous statement to me.
The meaning of words is derived from our experience of reality.
Words is how the experiencing self classifies experienced reality into a lossy shared map for the purposes of communication with other similarly experiencing selves, and without that shared experience words are meaningless, no matter what graph you put them in.
