So, the problem with your analogy is that you can call any cell phone from any cell phone.  Cryptocurrencies rely on the "network effect" in order to be effective, think of each alt-chain like a language - If nobody but you speaks the language, it's not very useful.  If everybody speaks the language, it's incredibly useful.   If everybody already speaks one language, and it's working fine for them, there is no reason to learn another language unless it offers some kind of tangible value over the one you're already using.

Telling me "Gold" is a good naming convention is, and being happy with that as it's only selling point is.... really odd.... In sales we call that a "marketing gimmick" - It doesn't actually mean anything, it isn't actually true, but it gives the impression of value where there is none by associating an unrelated product with something people associate value with.

I agree some alt-chains have the potential to teach us something about how Bitcoin works, but I don't see what coins like this do outside of try to sucker dumb money hoping for a price pop.  As mentioned before, I know why Miners want to work with something like this - It takes little time, little effort, and has very large upside when it's getting more difficult to mine real chains.    So want to try and explain this again with some actual reasons?
