Governments are going to accelerate the process if they want to have full control of the economy. Their main excuse would be to eliminate (or at least reduce) money laundering, tax evasion, and other illegal activities by phasing out paper money for good. But we all know there are other intentions behind this. Many say Internet access would be an issue for mainstream adoption of CBDCs, but satellites already provide the solution. Governments can spend on the necessary infrastructure to include even poor people in the system.
I'm pretty sure that CBDC will not help in any way in the fight against corruption, or anything else, it is of course only aimed at total control. How quickly this will be implemented, I don't know, but I think that it will happen quite quickly. You are right, there is everything you need for this, satellites, SIM cards, all this will allow to realize this plans.
When paper money is completely phased out and replaced by CBDCs, our privacy is seriously threatened as they can control our entire finances, even with the smallest expenditures. Using privacy coins like Zcash or Monero will also not be able to guarantee our privacy if CBDC is the main currency of the world. I mean, we still need to convert crypto to CBDC, which is very easy to expose our privacy. I really don't want paper money to disappear, it's really not in our favor.
Yes, we will have to show everything that we have if it happens that governments will allocate some time so that the population has time to replace fiat money with digital money. It's a very bad script, I hope it won't happen soon, now it's more like a movie script.
