CBDCs - good or bad for Ethereum and crypto as a whole?

I don't know how much information there is about CBDCs in your country or what they plan to implement, but here in Brazil the central bank made it really clear through several lectures and QAs what they're planning.

It sounds like they're preparing a private Ethereum fork to reap all the benefits of the blockchain and smart contracts and enhance our financial system, but of course with the central bank having admin powers over the network. Sounds kind of contradictory to have a blockchain with an admin, yes, but there are still some good points: we'll have asset tokenization, atomic swaps, AAVE style automatic loan liquidations, and everything that Defi does in real decentralized networks.

Basically people will deposit their normal money to a bank and choose to mint the digital version of it, and in there they'll have access to a gated Ethereum-like ecosystem.

The lead guy said the plan is to allow financial transactions that wouldn't be possible otherwise, as they would require a middleman that increases cost.

Thoughts?
