Internal combustions work, really well, today, and are not theoretically impossible. Not really the same.

Well, you haven't proven Ethereum's theoretical impossibility either. 'I think this might be a scam' is not a proof, no matter how many heuristics are on your side.

This paper does a pretty good job of laying out a formal, mathematical proof that pos doesn't work

They work really well thanks to the invention of the spark plug, the carburetor, the supercharger, and decades of iteration. For many years, they were objectively terrible.

Ethereum is three years old. ICE is 200+.

Somehow I think that at 3 year anniversary of ICE people had some actual real world use cases for ICE where ICE was still somehow better than steam engine and animals, even if ICE itself was objectively terrible?

Ethereum is objectively better in some cases. What if I want to gamble somewhere, but I don't trust websites to be honest about their odds? With Ethereum I could check the source code of the contract and be confident that it's legitimate.

Not only can you verify the code, you can verify that the code and the output wasn't modified during execution by some external actor.

A 1910s ICE might have been terrible compared to a modern computer-driven engine built on one or the other dozen million man-hours, but back in the day it was still a very useful thing that powered machines and vehicles and even had broad military applications.

ICE didn't work really well in 1910.

Ethereum works today as well.

I think you missed the point of the analogy.
