And what bitcoin does when it comes to their power? It reduces it, bitcoin takes away part of their economic power and gives it back to people, programmable money could even replace some parts of the government and the legal system, bitcoin can also make way more easy to hide your wealth which reduces the taxes they can get and the money they can confiscate out of you, all in all while bitcoin does not threaten them directly it has the potential to reduce their power in a significant way and they hate this.
The fact is that bitcoin was not created for anything that is anti-government regulation, but you as a user can have the option of minimizing the centralization of your finances compared to the fiat system you have been using. My first thought about bitcoin was that it is a currency that is useful as an alternative payment option, but probably won't replace centralized fiat.
I don't hate fiat for helping us financially and facilitating transaction before everyone had bitcoin, but here bitcoin has a better solution as a payment system with increased innovation that fiat could not have before. Bitcoin doesn't exist to replace the previous financial system, but it offers a better solution.
