More specifically, "to anyone outside of their own economic circle".

This is a hypothetical clause which would imply that, "if I mined Bitcoin, and sent it to my friend Vic, who knows I want him to hold on to it for me, and he's never going to send it to someone outside of our authority, and we NEVER EXCHANGE IT FOR ANYTHING,"

then it remains unissued.

However when someone transacts Bitcoin to someone else with the intention of no longer possessing it, that is when Bitcoin has been issued.

The next person is thus the issuer of that particular set of Bitcoin.

So miners are not the only issuers, because peer-to-peer money enables us to BECOME issuers.

But they are the "origin" of Bitcoin and procure 100% of it for us to redistribute.

So perhaps it is semantically a bad choice of words. But I believe the point is valid. I'll explore this further.
