Makes perfect sense. The US is the most wealthy-unfriendly tax regime in the world. I have friends who have never lived or worked in the US amd yet are asked to pay high US taxes. They hate it and will leave. The people who get naturalized are all people with no meaningful assets. Plus many global banks will not open us citizens accounts.
In other words being a US citizen is no upside and all downside.
