Satoshi's dream is still alive and It is fighting with the imposition of CBDC for compulsory use by all and the abolition of cash. It is the only way to escape the current financial system and central banks that is why they want to control Bitcoin price and with attempts to ban it.
CBDC's are already there but no they are not for compulsory use. Physical versions of fiats are still there and won't vanished because not all people are into digitalization. However, there are countries where cryptocurrencies are banned so people there do only have limited choices when it comes to digital payment methods and they may consider these CBDC's.
There is no way for the government or the banks to control the BTC price. Remember they are allergic with it and if they buy loads of it then it will be awkward. It is so contradicting. No one can control BTC price even its founder, which is why BTC is termed to be the most decentralized crypto.
