The question is, can forks of Bitcoin provide that utility in a significantly better way
Thats not really the question is it? It's not about better utility. It's about where you can unload the currency and for what/how much. It's not about usefulness it's ultimately about money. Real money. Bitcoins are only valuable in a world where there use is necessary. I wish I could bold that on HN, NECESSARY. Without the necessity any normal consumer would use a more convenient, less volatile system.
Lets shift for a sec. Think about the silk road marketplace. What they should really do is come out with a bitcoin clone of their own, get a bunch of early adopters behind it and then switch the website over to only accept their crypto currency. The'd rake in the cash and have a pile of it on hand from getting in early. They'd be selling the currency and the products you buy with it. The worlds best drug dealers. In fact theres no telling whether the bitcoin early adopters are involved in this very practice at silk road. It's not about beating bitcoin in usefullness, it's about real money.
Also, most currencies favor early adopters, even (especially) gold and silver. I don't think that's really anything new
Gold and silver don't compare. They're not currency, they're commodities that have actual use and value outside the realm of wealth exchange, and they didn't favor early adopters(thousands of years ago). That comparison holds little to no value and frankly I'm growing rather tired of people pretending like it does.
