Because the entire idea of "insufficient entropy" past an initialization amount is a cargo culted fantasy. In the Linux kernel view of the world, /dev/random "loses" 1 bit of entropy for every bit that gets read. That is not how cryptographic and hashing primitives work, if it were it would be dangerous to use an AES key to encrypt more than a few megabytes for example.
