What are the underlying values of Ethereum?

To put an example, the underlaying values of Bitcoin today is to provide digital inelastic scarcity with specific properties (security, divisibility, hard-fixed supply, etc) that make it "good money".

In the worst case scenario, it would serve as a store of value like gold: limited supply and inconfiscatability.

Given that Ethereum has very different properties, what is its proposition?
