what is your idea of a perfect blockchain?

if you were to create a blockchain from scratch, would it have tokens or currencies? should an economy have currencies at all? would you have the system itself designed to enforce fairness? would you enforce taxes on trade or wealth accumulation? do you like dpos, or do you prefer or systems? which blockchain that exists right now do you think approaches the concept of fairness the best? (you can ask chatgpt or claude if you need starting points for ideas - to be honest i ask chatgpt about a lot of stuff!) id like to hear all of your ideas! thank you, i hope you have a great weekend!
