In addition to the other comments, why would you start investing computing power (and therefore money) in a 'currency' that is centrally controleld. Just to 'take away said control'? There's no motivation for that.
To make it more decenteralised. Cryptocurrency without enough participents actively voting with their computational power is not a cryptocurrency and will have none of the improvements over fiat currency.
Bitcoin might have 51% dishonest problem but it can be made honest again by increasing total computation. Whether 51% are honest or not is function of total computation power [TCP]. Probablity of 51% being honest goes to 1 as TCP goes to infinity.
