Today I was attending a lecture about blockchain and cryptocurrencies and the lecturer said that freedom and safety don't go together. You can have more freedom by abandoning safety. Would you agree?
Agreed. History is full of unintended consequences, partially because so many things were more complicated than individuals and societies realized. There are not tons of really simple tradeoffs along the lines of 'freedom vs safety'. I don't think people could have imagined the future world they would bring about when they started planting crops instead of just hunting and gathering, for example.
