They have some value on the open market which is a function of how much people are willing to pay for Ethereum hosting and how much people think people will be willing to pay for it in the future.
For an example of Ethereum innovation, musician Imogen Heapis using Ethereum to create music sharing and remixing, with smart connections among artists, producers, and fans.

"her current project: to bring to life an entirely new landscape ... spurred on by the technology originally designed by libertarians to create the crypto-currency bitcoin, she’s releasing her next song as an event and an experiment. What she hopes to emerge is the core of a revolutionary system she refers to as Mycelia. It could completely transform the music industry."
At some point, a hard fork will be required for Ethereum that the community will not want because they've got vested interests that differ from Ethereum's developers.
Once the transition is made to proof-of-stake, the incentives of its "miners" will be more closely aligned to those of the community.
The existing miners can't prevent that transition. They're also using general-purpose hardware that can be repointed to other chains or sold to gamers, so they don't have a strong incentive to fight it anyway.
If the community ever loses confidence in the foundation's leadership it can transition to another arrangement.
But I'd only claim it's more resistant, not immune.
It sounds like what you're saying is "yes, big players will emerge but something will keep them in check." What is that thing?
Also, how fast does the blockchain grow in size in GB/month?
Blockchain size is increasing rapidly, I think it's up to 40GB already. But they plan to implement pruning before it becomes a serious problem.
