Interestingly, in Muslim Bitcoin communities, Muslims say that Bitcoin is the perfect fit for Islamic-based Economics and the best revival of Sharia's soul in modern finance.
The argument goes that all fiat is Riba (created money ex-nihilo), and Riba is one of the gravest sins. Bitcoin creates money through spending energy, doesn't have usury, and no one can create it arbitrarily. So, it's not Riba, and it's the closest we have to the revival of Gold as currency. Gold and Silver only are permissible currencies in classical Sharia. Everything else is impermissible as a currency, although some certain types of bartering are allowed. Bitcoin is as close to gold as anything else humans have created.
From theological point of view, Allah has declared war on Riba in the Holy Quran (2:275-279). The only sin that Allah declared war on. This is because creating value out of nothing is an illusion, and that's the creation of Shaytan (Satan). Creating value out of nothing is, in reality, robbing value from some else without merit; most likely their time, but possible stored value as well.
I'll try to read your longer post, and see if I can understand, but my understanding to Biblical theology is limited to basics.
