I suspect that were they to open up access to the iPlayer for non UK users and charge a fee in the region of Netflix's, the Beeb would fix their funding crisis. And as they would circumvent advertising concerns, there would be no threat to their impartiality.
I feel that were the UK to lose the BBC because of Hawkish government ministers who are ideologically opposed to public service broadcasting that values quality above commerce, than the loss will be not just theirs but the world's.
I would be very sorry to lose the BBC World service.
