The satire was not of money or central banking, it was of the public reaction to a new form of it.

Also, if you think that central banking is the greatest invention since sanitation, I think you may have your priorities slightly skewed, though that is only an opinion.

As to whether bitcoin is a currency. It is a currency when it is used as one. Sometimes it is and then it is a currency, mostly it is a speculative investment vehicle. This is why I think dogecoin is more of a currency than bitcoin at the moment.
