This point should be made more often. It also supports the ethereum and EOS use case, a general purpose computing blockchain and distributed vm, it allows smaller utility coins to be backed by the same size network as the eth token and ecosystem, something they would never do on their own. The token's security is proportional to it's network size. Fragmentation of the already small subset of people capable of running blockchain nodes that actually do run nodes is great for innovation but bad for network security and confidence.
