That's a lot of contortion to attempt a defiance of etymology. And anyway the conversation was about redistribution, that prefix of course demanding an additional contextual layer on which the word is applied. Trying to imply that in general redistribution should be ambiguous enough to be synonymous to concentration is firstly just muddying language to make conversation harder and second taking us further from the point of the conversation anyway. Since when is it in the interest of any discussion that "words mean things" becomes controversial?
Words mean things. This word doesn't mean what you want it to mean, either according to the other people in the thread you're interacting with, or the source you decided to cite.
Etymology is not the sole determiner of meaning. We can call an area on the moon a "mare", and know this comes from the Latin for "sea", but "mare" in the context no longer means "sea".
This word does indeed mean exactly what I want it to mean, you're cherry picking other aspects of the definition to somehow overwrite the original rather than to acknowledge that we both can be right in certain ways. I'm right about what this word literally means, you're right that carelessness wins the day when it comes to language drift.
