I couldn't find the article from Brave New Coin magazine but the below link also talks about the same thing,
https://www.forbes.com/sites/seansteinsmith/2020/12/09/cryptocurrency-legislation-is-on-the-rise--what-the-proposed-stable-act-could-mean-for-crypto/Government is just paving ways for CBDCs, at least that's how I see this draft bill! Government already knows that it is impossible to control a decentralized network so they are trying to hit the new peojects by asking them to register with Federal Reserve and complying with various requirements before they can start issuing stable coins.
I don't think government will come after the nide operators because it will be more like finding a pin in a haystack! Also US government can't control the node operators from other countries so even if they crack down US based nodes, illegally issued stablecoins will still be able to get confirmation from nodes operated from other countries! So it's just a waste of efforts and money by the US government if they want to come after the node operators!
Possibly. But I think the US government will shut down Fiat on/off ramps as a last resort in case all of its efforts become in vain. With heavy-handed regulations, it may be possible to block nodes located within an specific region. The government might require ISPs to block individuals running nodes throughout the country. Even connecting to nodes located in other regions, will not be possible. Of course, using VPN and/or Tor will allow anyone to bypass government restrictions. But not everyone will do this, as doing such practice will be deemed "illegal" by the government.
For the sake of the ETH blockchain, it's best for the government to regulate stablecoins directly instead of holding node operators accountable for their actions. By simply requiring stablecoin issuers to register as a money transmitter, the number of scams will be greatly reduced on the industry. Those who don't comply with the latest regulations will simply face prosecution from the government. It'll be interesting to see how everything unfolds in the future as stablecoins become more popular in the crypto/Blockchain space. Whenever governments will have a friendly stance towards the industry or not, it's yet to be seen. ETH may be decentralized, but Vitalik Buterin's large prominence on the project has a lot to say about it. Governments could pressure him to make ETH regulatory-compliant or face consequences. Satoshi never disclosed his/her identity on the Bitcoin project because he/she knew this would happen. Vitalik could've done the same in order to prevent governments from holding him accountable for his actions. We're going to have to see what happens in the future with stablecoins and ETH node operators as governments devise new regulations to enforce control over this emerging industry. Just my thoughts
