As far as I can see, there is zero difference between a) an electronic IOU each worth exactly 1 cent, which can only be redeemed in bundles of at least 1,000 IOUs, and b) a $10 IOU/lottery ticket with a 0.1% chance of winning.
In both cases the average IOU is worth 1 cent, and in both cases the issuer avoids handling very small amounts by only allowing redemption of IOUs worth at least $10.
The bottleneck here is the process of issuing these IOUs, which must be done by a trusted party in order to avoid the double spend problem.
