@EJB,
If
you think that quote means that
I think UA miles are worthless, you're less worthy of this debate than I thought

Contrary to your mistaken misinterpretation, "Your insistence that UA miles are worth something more than $0.00" does not mean I think UA miles are worthless.
"Your insistence that UA miles are worth something more than $0.00" means "Your insistence that UA miles are worth something
[how much you value them in in excess of $0 I don't know]"
The point, which went
whoosh, was that notwithstanding UA miles are worth some number, that number is less for him than it is for you, which I made pretty clear.
