An idea

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).

Aha- you want to peg our new currency to something we all believe in.

Now it makes sense that Tynan was the originator, this is all a complex trap which he will spring shortly, the great purge of the believers.
