Seems like that will just drive the foreign super rich to ‘buy’ citizenships too. With enough money and in-country fixers/ lobbyists, that’s usually not unobtainable in most countries.
I wonder if you'd eventually get a weird marriage for citizenship market from such legislation. Like say you are a modern millennial couple and both you and your partner don't care about the institution of marriage. Are you going to leave money on the table, or get a huge lump sum for both you and your partner to be legally married to some investors that you might never need to meet in person?
