First of all, you need to be awfully rich to be able to have your own piece of land surrounded by seawater. Well, say you happen to have a real fat piggy bank and would want to buy one out of a whim, here’s an article on buying your own private island. This basically lists the factors that you should consider when buying one, namely:
- Price
- Location
- Water
- Climate
- Accessibility
- Development
- Size
- Anchorage
- Topography
- Beaches
- Infrastructure
- Caretakers
- Utilities
- Land tenure
The list’s pretty much inconsistent with the title of “How to buy” since it’s mostly factors in choosing an island. But it might be because every country has its own provisions for land ownership.
Realistically, land tenure is the most important factor here. Different governments and constitutions have varying provisions for land ownership. If you’re lucky to be a citizen of an archipelagic country, then this trims down your problems. Some land/real estate laws do not award full (or even partial) ownership to foreigners.
Remember too, that to be the king of your own island, you must have the international community recognize it as sovereign. Until you get an island that has full recognition of sovereignty, forget about setting your own government. You’re still pretty much bound by the laws of the country that holds jurisdiction over it.
So if you have dreams of building your own republic that swears allegiance to your colorful boxer shorts, I’d say “Fat chance, but the best of luck to you.” Well, who knows…?
