Humans often aren't reasonable, nor are we computers with the capacity to instantly recall large sets of data (such as whatever billion digits of pi would be necessary to encode an image.) And U.S. law agrees: it's possible for numbers to be illegal, the same way certain speech is illegal, and in fact the same way certain images are illegal. It's mildly annoying on its surface but that dissipates when you stop and think about why things are the way they are. (It's possible I misread your comment and we agree.)
