Too true. The question should be being asked (Not necessarily by Douglas), what is the effect on money which is not issued, whilst product is being created and added to the economy, with effectively no real limits, that no-one thinks is valuable, whilst putting to use ever more amounts of it?

We put to use now more than tens of GigaJoules of solar energy per second in every developed country, and still no money is ever issued on it.

By Austrian economics, that looks like a growing problem to me, actually the real physical driver of inflation.
