What will happen when hiding even small illegal activities becomes impossible?
I was driving home today and the satnav warned us about driving over speed limit (74 mph on UK motorway). Ok. But the solution to that is technology - and organisation. There are speed cameras on this road. But most of the time they don't take images or don't trigger an action. If every road camera triggered a warning / fine on every violation then speeding would stop in a few months.
Is that something socially beneficial ? Probably. Would it be disruptive and cause great anger and political resentment? Yes.
That is one tiny example but I think that pretty much every criminal act can be detected with technology - it's going to become which one we care enough about to prosecute and which we give up and decriminialise?
Or governments will continue to have those laws on the books and prosecute them with discretion (which is what happens today). It is very convenient for those in power when every person is already guilty of something.
If society is not free or fair, that's the problem to fix first.
