I think you should be prepared to make sacrifices. Either to your lifestyle, your principles, your safety or your wallet.
Eg. If the new RUC system comes with GPS trackers, what will you do? Abandon your car, abandon your principles, or act belligerently?
If NZ introduces an adult-ID system like the UK, what will you do? Give up ‘adult content’, or pay for an overseas VPN?
Can you afford to protest? To stand by your principles? To circumvent the systems?
It likely won’t come all at once. It’ll be slow and incremental. But privacy will keep being eroded. In this modern age data is money, data is power. Privacy is the anthesis of that.
