Putting this up for argument rather than for agreement. I have read it twice and I am still not certain what it supports.
The trade-off is reversibility against privacy and there is no option that gives you both. Card payments are reversible and disclose the most; crypto discloses least and is irreversible, which is precisely why pressure toward it is a warning sign when it comes from a seller rather than a buyer. Escrow only means anything where the escrow agent is independent of both parties, which is rarely the case in practice.
Where I think it is weakest: the subgroup findings are the part I trust least — with enough subgroups something is always significant, and these were not all pre-registered.
What I am trying to establish is how people are thinking about the trade-off between reversibility and privacy, because you cannot have both. I would rather have one careful answer than five confident ones.
