Here's why we, the people, need privacy, security, and anonymity (the state can deem you a criminal whenever they want): "The Bitcoin network has a governance structure in which roles are assigned to identified individuals. Authorities could decide that these should be prosecuted in view of the large scale of illegal payments using Bitcoin. Decentralised finance can be regulated as forcefully as the legislator considers necessary."

I hear your point and it's a valid one. Consider the recent case of Tornado Cash and the Open Source Is Not A Crime movement. Two individuals were arrested for developing open-source code on GitHub. Just last week, GoFundMe shut down the Tornado Cash legal defense crowdfunding. This suggests that the state is more interested in protecting itself from individuals rather than defending their rights. This could potentially set a precedent where inventors or developers of decentralized technologies could be targeted, even if they've done nothing inherently wrong.
