1) Of course those are useful things, but lack of them doesn't seem like a serious issue currently, do I underrate such problems?
2) Fair enough. 2b) I would prefer it if you used more neutral language to describe our disagreements. Here's a good reason for you to do this: neutral language makes me less likely to get defensive and thus makes it psychologically easier for me to agree with you.
3) The NGDP thing: obviously I do not view NGDP as fundamental, which is why I usually talk about 'monetary disequilibrium' instead. I do think that NGDP targeting is better than currently used targets, and I haven't been able to think of significantly better rules for the money supply (including 'known increase in the quantity of money', like bitcoin).
I haven't read/listened to them, but I thought these might be interesting to the local bitcoin users:
Eli Dourado (GMU econ PhD candidate) on the economics of cryptocurrency.
Econtalk podcast - Russ Roberts (GMU econ prof) with Gavin Andresen, Principal of the BitCoin Virtual Currency Project on, Virtual Currency.
Roberts' podcast is always stimulating even if I disagree with him, and Eli is a pretty insightful guy who I've met in meatspace.
