Issue is when the government (or hacker, or criminal) decides you don't exist anymore and cancels (or steals) your credits.
The more you are divorced from cash transactions, the less you are aware of the transaction. You pay bills at end of month, and are dependant on your bank or card firm to alert you to irregularities. What happens when they don't alert you?
I avoid an Australian coffee chain in NY because they only accept credit or debit, no cash allowed. I'll buy coffee from a street cart in an instant. The duty of every citizen is to legally avoid taxation, and a cash payment simply makes it less complicated.

A government financial cyber currency system. Would have layers of security beyond what exists today. Even if the system was breached the person doing it would be on record. The next time he made or received a transaction they also would know from where it was done. Plus the system may be blocked from his use.

The bottom line for me is I would not want to see a system like a cyber one replace what is.

Other than if it killed the drug business and had a great effect on reducing crime. It is really disturbing that things like this are not far from people having implanted chips. What is almost certain if society deteriorates. There will be changes people will not want. This type of change is better than the emergence of a police state,

When this point is reached is unknown but possibly inevitable. Things like illegal entry of a country become impossible as well. There is no way for them to aquire money as it no longer exists. Or cyber currency. Since they are not on the data base there is no way for them to aquire it. Or spend it.

If you really look at it hard. Many of us already live with no actual money in our hands usually. It is a form of electronic credits system. The physical money in peoples hands creates many of the problems. Remove that medium and many things change.

I totally agree that the divorce from actual money is a great issue. At the same time it already exists and has already impacted too many negatively. For those that do not use the value exchange equation in their minds anymore. I notice more and more advertising is directed at them. This will grow as it is effective.

The people that remain responsible will still do it. Responsible in the sense they have some ideal of what they are doing. Those that are not it will make little change. It is just an opinion that things will change anyways. There are a lot of counter arguments. At the same time they do not stop eventual change.

We already have in effect a two type system in place. It seems to me electronic type money is winning. We might stop a lot of problems by the discontinuance of physical money. I guess the reason for this post to start with is the Canadian government seems to be having a hard look at it.
