Create a government from scratch.
Version control the laws.
Compare the laws with all other countries.
Hoard data.
Write code to replace government employees and to make laws easy to implement. (If done well consider selling a product or service)
Make everything modular so that the establishment can steal it.
Get people involved. Doesn't matter if you need to write a sim and convince them it is a game.
Pretend the whole exercise is writing code so that you can imagine you are perfect for the job.
I learn that people from all political angles like the idea of voluntary taxes (but no one believes it can work)
If the whole thing can run on donations and volunteers with a few "state" owned companies a hot swap becomes inevitable.
There are already N governments, why would making government N+1 improve anything.
I'm not sure you can code your way into having a monopoly on violence.
