There are two reasons bitcoin is worth money. Neither is because it's so wonderfully libertarian.
1) Bitcoin facilitates crime. it's really helpful for paying for illegal goods and services, money laundering, etc
2) Bitcoin is a ponzi scheme. It's like amway where the people who get in first get money from the people who get in later.
PS both bitcoin and etherium are absolute and total shit on technical grounds. here's one example from a few days ago. i've read many, many more. issues with bitcoin include limits on transactions, transaction fees, and the ridiculous problem that when someone pays you, you both have to wait and see if the payment actually happens or not, and you can be pretty confident the payment will be permanent after like an hour (but you're still not actually 100% sure).
