This is an efficient way of buying fuzzies, for a really cheap price, and it's important to buy fuzzies or you start to fade. If you want to buy utilons, find a maximally effective charity (this means you either check Givewell or pick your favorite existential risk reduction org) and donate more than $10. Do not confuse the two problems, and do not attempt to solve them both at the same time!
