I dont think listing serial numbers on ebay will stop bike theft; only bike sales (some of which may have been stolen).
And only if the seller bothers to Cross Check(a great bike btw, Surly) the serial number of a purchase against theft reports.
Ebay profits from transactions regardless, so why should they bother adding complexity?

Perhaps a more effective way to prevent bike theft is to do it directly? Start a petition to make bike theft a punishable crime; or if it is considered one already, petition law enforcement to, well, enforce.

-on second thought; the last thing I need is cops harrassing me for proof of ownership when I ride.
Maybe just start a petition for owners to not leave nice bikes out where they can get stolen.
