chaining together a few other tools like forking is free
By your reasoning, doing anything with the computer is not free, so why try at all? In my opinion, the cost of something like this is akin to the cost of gum balls: individually, they're so cheap that almost no one has a hard time justifying quantities of less than 100. And if you find yourself arguing with someone over the cost of a gum ball or 1000, just walk away. Your time is better spent.
Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
