Central banks use PID controllers to control stability [1]. Stable coin systems can use PID controller systems too [2]. Stable coins are as volatile as their fiat counterparts. Crypto currencies are run by people as much as central banks are. People can have opinions and values. People forked of Ethereum into Ethereum Classic because they had an issue with the main chain's policy. ETC community is alive. Building crypto currencies is all about optimizing for legitimacy [3]. We can build what we want, we just need to want it in the first place. No need to discount a whole field of computer science with a comment. - 1: https://link.springer.com/article/10.1007/s11403-014-0127-3 https://link.springer.com/article/10.1007/s11403-014-0127-3 - 2: https://github.com/reflexer-labs/whitepapers/blob/master/English/rai-english.pdf https://github.com/reflexer-labs/whitepapers/blob/master/Eng... - 3: https://vitalik.ca/general/2021/03/23/legitimacy.html https://vitalik.ca/general/2021/03/23/legitimacy.html
