There are numerous possible responses to this, so I'll list them.
1. If you thought I was implying I'm owed John's time or he isn't free to charge as he likes, you are mistaken. I am not mad that he charges.
2. I would be less broke if I didn't put all my time and money into getting strong.
3. Will you be releasing a manifesto soon, so that I may conform to your worldview?
4. What are you trying to accomplish with that remark? Where does it get you?
1. Good. I'm very happy that I misinterpreted you, and that you don't feel that it's a bad thing that a person gets paid for what they know.
2. You would also be less broke if you earned more money. There will be time for this eventually.
3. You are not required to conform to my world view. But when you imply that John is a prick for charging for his website, it leads me to believe that you think my work here is owed to you.
4. Perhaps I have accomplished it better with these remarks.
I'm glad we have come to an understanding.
