Yeah, I remember seeing the videos posted by the Navy during the Japan Tsunami. I think the ships rose 3 inches or something, then after the massive wave rolled under it, it settled back down a couple inches.

I can imagine, with no building codes, we won't have much cement on the island. All buildings will have to be earthquake proof, no doubt. It will be fun trying to figure out amongst a bunch of libertarians, how to construct buildings that do not infringe on others.

Talk about a grand experiment!

Don't worry guys, there's only a seven-year limit on chargebacks.

I'm sure that won't cause any problems for this venture or users of paypal in general.

as long as the "ground" is able to flex by about 5-10 degrees every 100 meters or so, i think would be adequate to be safe.

you could also make a bunch of platforms and just join them together with bridges, so if one goes down, they don't all go down lol

also, how do you keep the island from floating too much without having to waste a bunch of energy on motors and such?

how about food, import it all? or set up farms?

according to this http://wiki.answers.com/Q/How_much_agricultural_land_can_feed_one_person

300 square meters is enough for 1 person. id imaging this would scale some, and allow for dietary variety with about 100 people.

for 100 people thats 30km, square. depending on the meat to veg ratio (although i bet fish would be the main diet thing and i dont know how much that number assumes on hunting and fishing and such)

assuming it takes on average $75 per cubic meter of concrete to be laid, and the land or platform is .5m thick. 75*0.5*30*1000=$1.125m and that is just for the concrete to make the land to grow the food you eat, this would probably be higher, as i have no idea how much that $75 per cubic meter really covers. id guess its like $150 or even $200, as you are laying it in the ocean. this does not cover the cost of buildings or the soil you put on the concrete, along with roads and everything else. from start to finish, id throw out $100m or $50m if you are optimistic. although im sure the number could be in the billions.

another idea is everyone builds their own house or business to working standards and specifications. then people who agree to the same things, like laws and ways of government, simply latch on to each other and make a micro nation. if you do not like the way things and running, move your house or business elsewhere. when you make things this scale, overall it costs slightly more, but the cost load is distributed a lot more. so instead of billions, you talking maby 200-300k for the platform and another 100-200k for the house. if everyone had an efficient garden on their roofs, you could probably cover 10-30% of your dietary needs(one person, not a family).

Here is a tsunami wave for you guys, I can safely say that It's a lot higher than a couple of inches: http://youtube.com/#/watch?v=OdhfV-8dbCE

I'd use the navy or airforce.

Other than that: what's to gain for a country to invade this except bad publicity for murdering naive libertarians?

It will have to be done by majority rule, even though that sounds primitive. Or, it can be divided into different "ideology" townships, each with it's own set of basic rules and regs. One thing for sure, as long as there are computers and people go between this country and the mainlands, there will be a need for using bitcoins.

I hope the richest of the rich all move there,
then I'll jump on the first pirate ship destined to rob that place.  

It should be legal to do so, or at least not illegal, since international laws does not apply there, right?

We'll have a "Town Square" set up and waiting for you, with Hemp rope, so your neck breaks and not the rope.

Pirates that try to rob the place will be a favorite around town, when we have our annual "Human Hunt" on the island.

We'll be savage, and we'll be the most savage. After all, there's no law to stop us.

Oh man you are so smart! Yeah, they'll totally forget to consider tsunamis and storms when designing the platform. Haha LOL.

But seriously, do you even know how tsunamis work? That's a rhetorical question. You'll feel really stupid when you get it.  

In Russian "Utopia" sounds like something that is going to sink. Better give it another name
