It's amazing how some of you guys just "know" that something doesn't work without having tried it. Sorry you can't comprehend how it works, that doesn't mean that it doesn't...
Nobody is failing to comprehend how it "works". People are pointing out to you that this "idea" of yours is broken.
It's not a mystery. See every other service announcement promising to pay out more than was deposited on the basis of other people's deposits. Not just in BTC, but throughout time. Report back with which ones worked.
Again:
The payout sharing was just an afterthought in the first place thanks to user feedback. The original point of the site was as a way to convey (or "advertise", if you will) your Message. Which you can still do in addition to the 150% return.
The following verbiage is on the site's About page (which I have linked to repeatedly):
When you are the Ruler of a Nation that is conquered, you will receive your initial investment back, PLUS 50%! But be forewarned – if after 90 days no one has conquered your Nation, its people will become complacent and its whole value (as well as your payout) is subject to total annihilation – so invite everyone you know to conquer you!
So the nature and reality of the payout is explained completely upfront. Of course at some point it becomes unsustainable, which is why the 90-day reset is necessary. But my users wanted this model, so that's what I'm giving them. If you don't like it, don't participate. But that doesn't mean it's some kind of "scam" as nitwits are often fond of mindlessly repeating despite not having ever used or tried to understand my game.
