This isn’t specifically about the Pope, or dual or triple citizenship, but I have long ordered how it is ethical for a dual citizen to actually vote in more than one place.
I mean, I am personally a dual citizen and pay taxes in both countries, but I really don’t feel right voting in elections effecting the place that I do not live in.
The one person, one vote thing - as idealistic as it is - sort of matters to me… either that or I’m justifying my laziness.

Legal residents (but not citizens) in most countries do have to pay taxes.
Most places make you pay income tax if you’ve stayed more than 6 months a year while earning money.
The benefits of being a “resident” and paying taxes include living in a place that has “the rule of law” and borders that are defended, so that the next country over can’t come over and seize everything and everyone occasionally. If this all sounds medieval, it is because it is. It’s like being “under the protection of” the local noble/warlord.
Citizenship itself, in more abstract terms is interesting. It is a “club” that individuals can shoes to join and/or change per will? Or is it more like the state “owns” you and they don’t care enough to prevent you from moving around.
Remember, the US requires you to file/pay taxes if are a US citizen but live abroad. Most other countries do not require you to pay taxes if you’ve live/work outside of their country. Does it feel “medieval” yet…, where the most powerful “lord” can make his people pay tax even though they are living in another “lord’s” domain?
