It's right there in the name. Some people believe that their assets should not be freezable or restricted by the whim of their local government-of-the-week. Cryptocurrencies have obviously solved this problem quite well or people wouldn't be complaining about how it has enabled more cybercrime (specialists, include cyber criminals, are often quicker to adopt trends than society at large).
Moving beyond that, the utility of a cryptographic smart contract system paves the way for the future of the internet. People forget computers are less than a hundred years old, and that there are thousands of years of computing ahead of us. The fundamentals will look very different one day.
Speak for yourself, I grew up in poverty. I also said nothing about Libertarianism and did not endorse it; Please do not inject your biases, patronize or turn this into a straw man. Do you want to actually address my argument?
