Are you specifically including Bitcoin's fixed coin emission cap in your reasoning? It is known to be problematic. One of the things it apparently prevents is a flexible blocksize because that apparently requires a tail emission instead of fixed cap. Tail emission yields an inflationary coin (see Monero's economics) whereas the fixed cap of Bitcoin causes it to be continuously and strongly deflationary. I'm not an expert in QE but you're comparing a centrally governed fiat system to a system which places governance in the hands of strong social/financial incentives. Such incentives eventually lead to asking the most qualified person for guidance (which becomes governance). I'll be very interested to read your reply in case this modifies your thinking at all. Thanks
