I appreciate your perspective, but I think there’s a lot of space for charity entrepreneurship. See my response to Lila above, and let me know your thoughts :-)
I’d enjoy reading your reasons for this in a top-level forum post. I expect others would do, and there are certainly plenty who think like you do who could participate in a comment thread discussion of this, which your post could trigger.
I thought that a lot of this stuff was already covered in this post and the links there: http://effective-altruism.com/ea/q6/new_project_announcement_charity_entrepreneurship/ It seemed to have been positively accepted without much commentary, so I’m not sure others would have a lot to say.
