It is very amazing technology and I believe using that tech to ensure in practice that something so fundamental to our freedom and life cannot be arbitrarily manipulated. Money is to the convenience of the people not governments or private institutions. The security aspect is also important. I can't tell you how many times I needed to ask my bank for a new debit card because my account was accessed without authorization. I am a very careful and paranoid person but I can't stop crafty people from scamming magread swipes. The U.S has finally stepped up in this aspect with chip readers but there are still many ways to lose money through no fault of your own. Giant corporations get hacked and credit card information gets stolen and sold in the deep web.

Privacy is inextricably linked to our liberty. If we give it away we give away our freedom for a little convenience. Not a fair exchange in my opinion. i am optimistic though humanity will instinctively seek freedom. It may only be the brave few but it will be sought.
