At this point I'm reasonably sure there is not enough consensus on the interpretation of the word "currency" to make any meaningful statements about what is or is not one. And the same goes for many other words that get thrown around in these kinds of discussions.

I'm sure there are lots of people who feel that they know the "correct" definition, many with a compelling justification for its validity, but without consensus the word is little more than a rhetorical value judgement.

If people want to have meaningful discussions about new topics which fall outside the established semantic shorthands of past discussion, it generally better to avoid those words entirely.

There are lots of unambiguous claims one can make about Bitcoin, and I really wish people would talk in terms of those, instead of endlessly arguing about what names we're allowed to call it.
