It's a great concept on paper, but so poorly executed. People certainly have the right to be sceptical about the record with data scandals like Facebook's Cambridge Analytical.
I've opted out. Perhaps I'd consent to a health record that is encrypted, decentralised, and linked to a MyGov account (prferrably with improved security).
there are plenty of things which work on paper ;)
I think the governments track record of lies and deceit speaks for itself, the less power we give the government systems the better. Also regarding consent, looking at their actions.... i don't think they give a crap about it , lolz.
