1) It appears to me that the document you provided actually refutes what you are saying. It supports fractional reserve banking. Here is a quote from the conclusion: "Most of the money in circulation is created, not by the printing presses of the Bank of England, but by the commercial banks themselves: banks create money whenever they lend to someone in the economy or buy an asset from consumers. "

2) "infinite money" without a legal limit to reserve ratios would only occur if every single bank actually had exactly 0% reserves, and it would take infinite time and infinite transactions for that to occur.

FYI using the observed absence of 'infinity' as a proof is generally poor logic as there is lots of mechanisms blocking infinity from occurring in reality.
