Modify #1 to "The value of the currency is the average effort required to obtain X in wealth."

That allows us to include inheritance of wealth and finding bags of gold in the street without dismantling our understanding that a given amount of money represents a given amount of effort that we can expect others to be willing to exert to acquire that money from us.

And then walk through a house and look at it not as $X00,000 dollars, but rather as the amount of human work it represents.
