Neither are public information. The current registered address is, amount of taxes paid - yes, these are public (although for the latter you have to pay some very small fee, IIRC).
I believe it varies between countries. Where I live the actual address does not really matter for most intents and purposes, what matters is one's registered address because that's where paper post goes, and more and more people use e-post even for government communications. Where my parents live it is actually quite common to _not_ live where one is registered, especially among younger generations, this is because police first comes after you to the registered address, and police in that country is often more dangerous than "no police". So I do not speak for the "vast majority" but for the people around me.
Case in point: if you are well off enough to rent or own multiple properties you have the privilege of not being doxxed by these brokers.
Tell me again how knowing 18 year old Sven Svensson earning $10k a year at a part time job and renting in flat B69 is oh so essential for an open society again.
