I didn't say either Air Miles or Club Card points were convertible/fungible: both are proprietary currencies.
Air miles is fundamentally not a currency. It's a kickback. The institutional support structure that maintains it is kept in working order because it's backed by the marketing department of a major corporation.
It's not a way to build a monetary system - it's a tool to introduce principal/agent problems in other organisations.

While Air Miles may not be exchangeable between customers - although as far as I know they can be used to provide tickets or benefits for other people - I would suggest that they are a very long way down the road to being a currency.
Although of course I never said thet are a currency. All of this nit-picking serves to distract from the main point.
