The GP phrased that way too much like an allegory from under a rock and not enough like an internet comment. (I think) He means that digital currencies remove plausible deniability. The Polish government can both claim to crack down on gambling to its conservative supporters and at the same time avoid investing too many resources in pointless anti-vice enforcement. The second they have a digital ledger of all transactions in the country, they either have to get real with their conservative supporters who will vote them out or really go after all the people gambling whose bookies will drag them out from their beds. Politics is a balancing act.
