The danger comes when there is the implicit tentation to gather information on what we spend money in, how much we earn, how much we save month, etc. Only the information on what we spend money in would be a gold mine for a company like Google, Microsoft or Facebook/Meta, so they can step up even more their targeting ads and make more money out of them.
That is an implicit danger against our privacy many are not willing to accept just for a bit more con convenience.
That is what the big banks and big tech companies are
already doing because people use credit cards and banks sell your information. That "implicit danger" has
already been accepted by consumers--including most holders of Bitcoin since they mostly use centralized apps and brokers who act just like any bank or tech company acts.
All the anti-CBDC hype is doing, as near as I can tell, is drawing attention to something that is... already happening and has been happening for years--but is actually worse than what people say
will happen since it's unregulated private companies doing this to people.
All that said, this whole discussion makes me question whether CBDCs are even necessary when a private high-scale digital currency would accomplish the same thing for consumers. Maybe that future we all expect where there is no longer paper money or metal coins will happen without the help of governments. In other words, maybe USD will just be the measurement mechanism, but the actual technical means of transfer will be something we tech people invent.
At Haypenny, we have the "USD equivalent (USDE)" concept, which allows users to just show USD values for everything, with the currency's value being calculated in the on the fly (our system has to have this value around because transactions must always cost "a haypenny", which is $0.005, which means we need to know the USD exchange rate for every currency so we can charge the transaction fee).
So I've come full circle here
.
Store your wealth in an account that takes positions in a variety of investment instruments based on your view of what will be the most valuable in the future, and convert that to a widely accepted, private, privacy-enhanced digital currency when you want to spend some of it at the retail level. And keep track of it all in "USDE" so you know how much things costs, how much you are getting paid, and how wealthy you are.
That is the future: USD stays around forever (and becomes even more predominant, worldwide, than it is today), but
only as a measurement standard and nothing else. And on a day to day basis everybody transacts in digital currency as the technical transaction mechanism.
