People often quote that line like it is a bad thing but somehow no one ever seems to pay much attention to the last phrase

... maximize the total amount of work performed in service of the community

I happen to think that is a good thing. This is not a lottery where the benefits flow to a lottery promoter or operator. The "ticket sales revenue" here takes the form of producing valuable content and participation as public goods. In economics we know well that public goods are often under-produced and finding ways to pay for them effectively can be very challenging.

The psychological effect described in the white paper may or may not play a big role (no one can really prove this either way). If it does I say so much the better.
