That's a lot of money, but on the other hand, if we take into account that the US recently approved as much as $40 billion in aid to Ukraine, or that the EU pays Russia about $30 billion a month for oil&gas, then it could be funded by a rich country or perhaps a wealthy individual like Mr. Mars.
The US and the EU area are trillion euros economies, imagine if the EU would plan to build a new capital and the price tag would be 15 trillion, do you see anyone agreeing to how marvelous such a plan is?
And it gets worse with every step down because once you force more on % the income it depends on how much of that income you have to spare, Germany could throw billions at something (the Berlin airports for example) but here we're talking about a country that spends percentage-wise half of the budget others do on education.
As for rich people that would choose to finance it, why would they?
What money can you get back from a city with no taxes, no vat, and no income tax, but full of running costs?

Let's fix this a bit.
He ordered some guy to buy 500
BTC with government funds, not from his own pocket.
It's easy to buy every dip and don't care about the value of
your investment when it is not
your money!
Just as he will not spend a dime on this city, it will all come from other people's pockets.
