A large number of blind people do live in poverty. Any additional money that is required to accomplish an everyday task is going to be an issue. I think there are potential ways of getting around that through what they call assistive devices programs—programs funded by the government that can assist with the purchase of these essential tools. But absolutely, any time you add a cost to a group whose income is already lower than the average, it's going to be an issue.
With respect to using orders in council, I think that's an option. I think it might put a bit of the burden on the users to say we need them to do this, rather than from the outset saying that this is how we're going to shape it so that the burden isn't on the consumer.
I could see it working, but I'm a little reluctant because it does seem to place a bit more of a burden on the consumer.
