The US government requires traders to give them US dollars whenever a trade occurs (i.e., taxes). This requirement is forced at the point of a gun. The US dollar is, at its core, a type of ticket that you must give to the government to allow you to live.
Don't take this personally, but the way you've formed how this world works is honestly gloomy and hopeless the least. It's not a surprise you don't find value in bitcoin, because you neither find value in freedom, privacy and censorship-resistance either.
Fortunately for the rest of us, this world is consisted of people who perceive things in a different way than you do. There's an admiring number of people who disagree with your assertion. Bitcoin is, therefore, valuable for those.
Odd. I would've made the assumption that if someone wrote what I wrote that the writer is anti-taxation and anti-fiat currency. However, the fact that I am anti-taxation and anti-fiat currency doesn't mean that I am oblivious to the fact that I must give the government those pieces of paper to live.
I am also not oblivious to the fact that ANY currency requires the sanction of the government. That is, the government can easily make that currency next to useless by banning it. This means contracts denominated in that currency is unenforceable. You cannot build large enterprises relying on unenforceable contracts. All that you can build are criminal organizations where you need to hire your own mercenaries to enforce your contracts.
Bitcoin, even if it has some value that I've yet been unable to identify, is not a solution to government force. The only solution is philosophical in nature. But that's a different matter all together.
