An interesting idea but the whole point of a passport is to prove which country are a citizen of. Countries set their visa policies to accept or deny based on passport origin. A US passport can get you a visa quickly in most places in the world but a North Korean passport would likely not. If I can simply pay for a World Passport, what incentive do they have to diligently verify my documents? Obviously a country could produce fake passports for their own citizens but that would be for some specific reason like espionage. Maybe a small country would produce a passport for me with a big bribe but I'm guessing the countries willing to do so are at the bottom of the list of "most accepted passports". Allowing anyone to get a passport with little scrutiny just devalues the passport. Perhaps in a more enlightened time, something like a UN passport would allow stateless people to travel easily to countries that would accept it.

No, most countries allow you to purchase a citizen and depending on your ancestry or knowledge of several country constitutions you could just walk in and demand citizenship.

St. Kitts & Nevis, accepted over 100 places, fairly powerful, purchase price at about 100k. Real estate can be a trust where you have partial ownership of a parcel which value is in excess of any amount needed to prove financial interest.

Antigua and Barbuda, same 100k gets you papers and a passport in a week with 150+ countries.

Price doubles for St. Lucia, but you're talking about 150 countries of visa free for 200k.

UN passports actually are highly suspicious, simply because of the diplomatic ties it contains - and bad image you can present the country in. You're there to highlight a political event, not to take leisure or secure travel. Very different circumstances.
