I'd say each to his own, but does money work if it can't be used as money? Can Bitcoin holds its' value if it doesn't ultimately become both SoV and Currency? I don't think so, you just can't have one without the other, or can you? One could use gold as an argument, but when gold was reduced to just SoV it also lost most of its monetary demand. The problem is, NGU need that monetary demand to keep Bitcoin healthy and strong.
