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).
