Bitcoin was developed on the idea that no one can be trusted and that everyone will act selfishly for their own self interest. This is patently not true, while many are selfish and are not to be trusted, a truly trustless society does not and cannot exist. People do come together and work in collectives and organisations and people do defer to the expertise of others. Imagine not being able to go to the doctor without first getting a medical degree because you can’t trust what the doctor will tell you or having to learn electrical engineering before having any electrical work done in your home. That is the ideology that helps spawn the no middleman trustless system that formed bitcoin in 2009. The truth is people don’t want to do that an the easy way to demonstrate this is to simply point at the huge amount of transactions that occur off-chain through exchanges (who serve as middlemen) vs the pitiful small number of transactions that occur on chain.
Trustlessness comes with huge costs. Firstly, you have huge amounts of redundant work to prove/verify everything. That’s why bitcoin is so terribly inefficient. Rather than having some you trust approve a transaction you now need to spend huge resources solving useless puzzles to prove that your transactions is the real deal. Secondly, without a middleman there is no one to hold to account. Make a mistake on your transaction? Your money is gone. Get scammed? Same deal. Accidentally leak your private key? Ditto.
Bitcoin is also based on the ideas of Austrian economics. Basically a ridiculous field of economics that doesn’t work. There are reasons why we left the gold standard and there are reasons why so called ‘sound money’ is a terrible idea. Just to simply illustrate. Bitcoiners love to celebrate the first transaction for real world goods using bitcoin. Some guy bought two pizza’s for 10000 btc around 2010 or something. They mock now for how much ‘money’ he wasted on two pizza’s. What good is a currency if you’re too afraid to spend it because its ‘value’ might skyrocket. In no uncertain terms Austrian economics is incredibly stupid. Bitcoin is built on this ideology.
Also Bitcoin is full of middlemen. Mining pools tend to congregate into large organisations lead by a small group of individuals due to economies of scale making larger pools more efficient than smaller pools and, because bitcoin has no real economy underneath it everything has to run back to fiat currency at some point. Whether you’re a baker or a drug dealer you have bills that need to be paid in fiat at some point; therefore, you need to exchange your crypto to fiat and, this is almost unanimously controlled by large exchanges who act as middle men. A big government like the US blocks the exchanges and bitcoin and crypto in general basically dies.
So in summary, bitcoin is based on the idea that no one can be trusted, which is false, that Austrian economics is a good idea, which is wrong and finally that it’s free from middlemen which it isn’t. The assumptions that made bitcoin are wrong.
