I chose "other".
On human lifetime spans (disreguarding evolutionary/biological change), I believe the form of government that generally comes into existence is all about economics (austrian/praxeology/game theory) interacting with technological changes. Evolutionary changes are just like technology changes.
Basically we individualists want a real context/"game" (game theory) where individuals have the greatest ability to protect their property. Technological changes change the game.
Here's what I'm looking forward to:
1. Technology is developed to assist the individual's property from theft. (note: recently created: bitcoin/blockchain technology)
2. Productive individuals begin to adopt the technology and lose less market purchasing power (only at early stages)
3. Government begins loosing purchasing power due to loss of income through theft (inflation theft no longer works, tax/confinscation not possible)
4. With government having less income, less market purchasing power, it must shrink in its operational ability. This is because government consumes resources as it performs actions. If it has less resources, then it must perform fewer actions.
Fighting this process is general technological progress that increases efficiency of food production and food to the sheeple, and then the sheeple's sheer power in numbers, and their being led by the power grabbing manipulators (men behind the curtain).
