It's true that the president in South Korea has very big powers, but Bukele is still some kind of dictator (that's what he calls himself) who does whatever comes to his mind and obviously has no one to whom he must answer. The Polish president does not have such authority and can say whatever he wants, but it is not of much use if he does not have the support of the parliament.
I don't know why people continue to call the US president someone who supports BTC, when on the other hand he obviously prefers altcoins, which he has already shown many times. What people should know is that most politicians are focused on their positions and profits, and they don't really care how they will achieve it.
Bitcoin is a hot thing right now, but that doesn't mean they love it or care about it.
Alts can be controlled, whereas BTC is only affected to some degree by third parties, countries and companies alike.
It can only be halted on its track to proper adoption.
