Yes, the treasury bond you mention is an example of a "loyalty program" or its "points" in the sense I mention. However what percentage of the population buys treasury bonds? (Serious questions). Most users simply do not have any special rewards by the government for particular use of their points. Being able to withhold something from taxes is one of the major ways that the government incentivizes certain spending, and it works. But to be very clear, I am specifically talking about "ribbons" and plaques and non-monetary types of acknowledgment that the U.S. Government could give in exchange for certain uses of its points, i.e. certain specific uses or accumulation of its cash. Acknowledgments that have no monetary value. So in this sense the Government doesn't do much. Do they even send you a "thank you" letter if you buy a 10-year treasury bond? This is what I'm talking about. Entirely non-monetary things that only exist in the realm of points and acknowledgment -- not things with actual true monetary value. This is a powerful train of thought that is unexplored entirely.
