Of the many crypto problems I can think of, reversible transactions seems low on the list. Tradfi "works" because there is no other choice given so people make it functional and it is comfortable through familiarity.

People conveniently forget the rampant scams, identity theft, and numerous types of fraud that are clearly irreversible in tradfi. Then they present it as a new problem that crypto must solve as well as being the same as the old system.
