"Bitcoin privacy" is a contradiction in terms, as has been repeatedly proven.
You set up a scene of a refugee "storing their wealth in Bitcoin", but it begs the question: where are these refugees with substantial wealth they are looking to exfiltrate? Typical refugees are emigrating from locales where they were earning dollars per day. The use case of shielding hoarded wealth during a journey to a freer locale is a blinkered fantasy. (Of course, if this is incorrect, surely there are hundreds, at least dozens of compelling case studies by now?)
