An idea

This part of the article is interesting:

"All businesses have to report all turnover and as every local currency is tacked to sterling, every sale, whether paid for in cream cakes, polar bears or carrots must be reported to its sterling value, the HM Revenue and Customs says."

Insofar as if we peg our currency to units of work, be they time or goal based then we could have grounds for saying that our currency is not related to sterling and is therefore not subject to taxation.

There are one or two issues related to that just as a concept, but we'll ignore those for now.

Tynan wants to peg our currency to Sterling - this is the only practicable way to operate a local currency. If you want to link our currency to units of work, then we introduce all the risks that the people who will provide this work default on that promise - the level of trust we need goes up, as we don't have the option to convert back to GBP (something we all believe in).
