Here's an easy one: the ability to receive a payment for a service without relying on a third party to deliver that payment.
New: state-level actor(s) cannot stop an organization from receiving payment merely by forcing your third-party payment processor to freeze funds/stop payments.
Example: sci-hub. If they were receiving payments through Mastercard/Visa it would have almost certainly been frozen long ago. However, since they (apparently) get funded by receiving Bitcoin, they continue to operate. In the meantime, grad students and professors get the convenience of using sci-hub's interface to easily retrieve journal articles.
Even if sci-hub eventually gets taken down completely (or a researcher finds a catastrophic bug in all cryptocurrencies), the total time during which sci-hub served documents funded by Bitcoins was a benefit to society.
ETH allows fancier transaction scripts than Bitcoin, but the same argument holds-- a state level actor cannot just stop the contract from being executed simply by putting pressure on a third party.
Based on this article, I'd say there is value in ETH just as there is value in writing a complex, multi-threaded application in a memory-unsafe language. It's a bad idea, but for some special cases it may be better than doing nothing at all.
