I see your point but in a way it supports the OP's point. It's more fun to just build new stuff instead of maintaining old stuff. That's why most hackers don't care so much about the business and just want to make things.

It's a bit like how some artists feel about their work. I used to write plays in school and college, one of which got really popular. People would keep asking me to perform it again and again because they loved it. But it killed me to do the same thing over and over again. I just wanted to move on and make new plays.
