I can consider these as greater control by the state over the funds of each person.

This got me hooked, but unfortunately I didn't get to see more backing it up.
CBDCs seems to be an obvious attempt for the government to have greater control over their citizens who are now digitalised. I think for that purpose it is discouraging people from buying into the idea of CBDCs thus, the reason why most countries fail in attempts to introduce it, while few others stops after introduction. Taking the digital Bolívar began, as example.
Good luck in the contest.
