I don't know what that propaganda would look like.

Are you saying that it would necessarily be achieved through propaganda?

We can't say apodictically that such propaganda would fail, whether it's successful or not is an empirical question.

I'm not asking specifically about the propaganda unless the propaganda is the only way to bring it about. I'm talking about the actual transitional method through which abolition would be implemented. Wouldn't the maintenance of abolition of money require an amount of resources which could only be procured in an environment where market prices exist? How would the economic planning necessary to amass these resources occur absent money?

Bear with me, I don't know if this next analogy completely works! I'm also thinking of a WW2 resistance fighter.

I don't think this would nullify the concept of demonstrated preference, nor do I think it would be a performative contradiction. I'm not sure this analogy really works given that the use of money isn't the same as joining the army or being conscripted. The use of money doesn't create victims as where military action does, including victims of taxation.
