Goodhart argues that states have essentially always been in control of monetary systems. He emphasizes that governments have always viewed seigniorage as a useful form of revenue and are unlikely to allow this source of revenue to be replaced by a private source of money.
Right now, Bitcoins are effectively irrelevant when compared with the larger payments system, but those who anticipate it expanding to be widely used might ask how sure they are that private monies of this type would actually remain private. Once big enough to be termed a success, any such currency would attract more attention from governments than a cursory Senate hearing.
