Huh? You can trace bitcoins forever, and people would probably pay extra for some vanity bitcoins; and probably pay less or nothing for some bitcoins that are legally questionable.

Your answer does not answer anything. The discussion is about whether or not to have the trusted third-party. Pro-ttp said that ttp protects from criminals. Anti-ttp said that ttp can make your own money dissappear because ttp is bending the rules. You said nonsence, your examples are not showing any rules or contracts about digital property which are being bent. Why any bitcoin criticism from anyone is always so weak?

All bitcoins are legally questionable; but no: ones that can be traced to contract killings not just stealing do not trade at a discount.
