Perhaps Eliezer doesn’t directly value fuzzies or status, so when he is purchasing them he isn’t purchasing utilons directly. Rather, he is purchasing motivation to continue doing things which directly purchase utilons. In other words, he doesn’t really want fuzzies, but if he doesn’t buy any, he’ll lose his motivation to be altruistic altogether. So he buys fuzzies to keep his motivation up which allows him to keep directly purchasing utilons—the things he does actually value. That’s at least how I read it.
