There is no reason for the march of technology not to destroy the issuance of currency monopoly that central banks have.
As money becomes completely digitilized.i.e the loose change and notes transfer into bits and bytes on your mobile, the power to create currency will be come democracized.It will filter down to any one who can offer a mini-bond that can be freely traded and whose buying power /convertibility and liquidity will be instantly available on tap ….on your phone.Companies will do this as vouchers and miniture retail company bonds start the ball rolling.
Then people will start doing it.Like a barter economy at first.But it will become a a currency if it becomes successful enough and is liquid enough.Transparency and liquidity will come from technology and also low costs .The low costs will allow this to filter down to even the individual offering his own bonds/currency.
Therefore…central banks will lose the power to create , inflate a antional currency…or they will have to live in a world where they have to accomadate competitors.
Older people may resist and cling to national currencies and the younger generations could be the main drivers at a micro-economic scale.
Mobile companies allow the trading of their credits already in Africa , so it has already started.
Welcome to the new world.
Long term , this will be another nail in the coffin to the idea of a ‘Country /Nation State’.
The Old clinging to the national currency and political structures , the young fleeing to less onerous tax environments ( and avoiding the rising costs of looking after the Old ) will be the main picture for the end of Nation states.
