It may be unintentional on your part but the above paragraph reads like you've made an assumption about what netgraph is and how it works and have decided that it's inefficient and therefore of not much use. Netgraph is great, but not because it's free and there is source. It's great because conceptually it's like lego, and in effeciency it's very quick. Netgraph hooks in device drivers are extremely useful. Who's smoking anything? You or me?
