Posts count don't set the character, it's just there to filter out trolls, so please don't use as a argument.
The main post is a bit hard to read, you may might need to break it up a little better (dyslexia whoo hooo).
That out of the way I have to say that it's very hard to figure out the value of things, as some people might even value flying into towers as a greater value than their wife, kids and friends. What is the value of a currency? It's all about how many people use it, and that's all we can really say, and then in the future we can tell what really happened.
Even if there is something wrong with Bitcoin it does not matter, there is something wrong with religions and statisme, and they are super big. There are some really skilled people on Youtube that produce amazing content, and they have few viewers, and there are these who get 100000 subscribers underservingly.
Value is a unknown variable, only testing can take samples of it, and only marketing can alter it.
Consider this scenario. Let's say you have a guy who likes to work on cars. He wants to run a mechanic shop. Let's also say that there's a global currency, x. Who are the customers that are going to be able to have their cars repaired? The ones with greater amounts of x and x only. But, if there's no global currency, then the mechanic is going to have to be much more thoughtful in what he could accept as payment that would be of value to him. It seems like this may help eliminate the huge gap between the very rich and very poor over time. I agree with you that figuring out the value of something is relative. And that's why I think that any global currency will fail under the weight of its own problems. If you place value on the process of exchange, then it places value on the relationship between exchangers. I just think it might promote social harmony. Global currencies create classes of social rank, and with it, greed.
