Server Idea, Minecraft Countries

I had a idea for a server I came up with after history class. What if there was 20 or so islands in the map and there is a barrier so you cannot leave this area. All of the islands are pretty big, at least 2000x2000. You could claim territory, form towns, and form countries. As a noble rank you can declare independence, but then if you are within a town or country they can kill you and take your things and land. Same goes for towns declaring independence. You can take land by force, where you can kill all inhabitants of that territory, earn territory diplomatically by negotiating with the owner, or colonize land that has no owner. Plots are whatever size the town or province/territory owner makes them. A chunk is a 30x30 area where the owner can do whatever he wants with, however they are expensive to maintain and may require people moving in and paying tax to support. There would also be a rent system where plot owners can rent there plot to others. If you go bankrupt you lose everything and have to start over. If you own a plot it becomes for sale by the town owner, if you own a town, province, or territory they disappear, if you own a country the land becomes neutral and available for colonization. This is only a start, we can have trade, religion, different types of government, and much more. Here are the abilities per rank.

New: No Perms

Peasant: Earned after 10 minutes of playing, but you may only earn money by performing labor, such as digging, mining, and cutting wood. Can only rent.

New Citizen: Earned after 2 days of playing. May own a residential plot.

Citizen: Earned after 5 days of playing. Can go to school and earn more money from job or shop. Can now own commercial plot and sell items.

Wealthy: Earned after a week of playing, earns a small percentage of the income of the town. You can claim up to 3 plots in a town or province/territory.

Noble: Earned after a 3 weeks of playing. Can claim up to 5 plots in a town our 1 chunk out of a town. If out of country, it can declare itself a province of another nation with its approval, if not approved or you choose to, you become a independent territory and be exposed to attack. Given the permission to use country chat.

Mayor: Earned by 4 weeks of playing. May form a town with a country owner or governors approval and have all perms inside town. Towns cost less than provinces/territories to maintain, but it is more expensive to expand, town chunk claim limits controlled by country owner.

Governor: Earned by being chosen by a country owner and having rank Mayor. Permissions are modified by the country owner but your basic permissions are that of a mayor with the ability to approve towns.

Country Owner: Earned by being chosen by Admin or Mod and having rank Mayor. May form a country and has all perms inside its borders.
