I’ll run out and patent the concept of Left, Right, Inner and Outer Joins. However, I all be Reasonable and Non-Discriminatory and charge 10 EUR per quarter per each occurrence per program plus a run-time fee of 0.50 EUR per invocation. It’s a reasonable fee since its so small and its non-discriminatory since everyone has to pay up.

Since we can’t know how many times you read that book, and it may be possible to lend out that book, we’ll have to round up and burn all non-DRMed, non-electronic books. Only the drm’d electronic books will be capable of even coming close to proper accounting. For thinking of literature plots, whether for writing or just reminiscing about past readings, until we can do the drm chip in the brain, it’ll have to be the honor system via a flat tax based on each nations literacy rate.
