My point was not to try to refute his arguments. He has good reasons and tons of experience.
That said, there are still people who are going to do startups on their own anyway and some will be successful. I wanted to share what's worked for me so far.
Not trying to be rude, but it seems like the piece does devote more space to defending single founder startups than offering advice. I think that's why I'm not alone in responding to it on that level.
I think you may be reading more into it than is there. I don't feel any particular need to defend them.
The background I began with was to provide clarity around why people advise against going it alone and some creative ways of making it work when you don't have the natural advantage of co-founders.
