That's the minimum viable product thing - you need to figure out what's actually helpful to people.

For instance, I hope some day someone takes up the mantle and goes out making a decent free identity system. I think most of the North European countries have one of those, and they are all proprietary and suck with no interoperability. If think there's government or even EU money to be had for something that works.

So basically, every citizen needs a way of authenticating, e.g. to submit tax information, log in to banks etc.
