I would love to force people to pay for things I love to do. There's nothing wrong with teaching philosophy, but stealing money to do so is wrong and lazy. What if I'd rather my money go toward cancer research? This guy would deny me that opportunity. He's saying his preferences are more important than mine. There are plenty of ways to make money teaching philosophy: donations (see FDR on Youtube as an example), books, speaking at conferences--but that takes hard work and risk. And if you can't make a living, why not teach philosophy for free as an avocation? Contribute as if it's open source -- for the better of the community. Stealing money from people and justifying it after the fact seems unphilosophical.
