You are correct! I'm American myself but my heritage definitely comes from Germany!
Thank you for clearing up that I was completely wrong in my first statement. :) I characterized that decentralization is the only key while that is certainly not true. I would also argue that immutability is also key as it stabilizes anyone's belief in their holdings. In fact I believe that's where I meant to go but just got started on the wrong foot and ran with it. I believe I meant to describe immutability the entire time but that doesn't discount decentralization at all either.
If the coins we hold are not immutable then what is to stop the majority from deciding our holdings on the chain. While I agree this seems tolerable in cases of known theft or fraud but how can we decide? If it's merely the majority then I just need enough economic power to say that my target is a bad actor and I can eliminate their value to the system by creating enough ill will that someone takes away from them.
Even worse is if you are the opposite of the majority. What if 51% of the chain is held by Americans while 49% is held by the rest of globe. We could simply say that we don't want to share our economic value and cut off anyone that we don't seem to fit our standard of the majority.
I think the solution is as you said to @anasuleidy to not allow them in your house or community. While we certainly can't force them out of the world (Steem) we can ensure we don't allow ourselves, or our like minded community, to interact with them.
