As far as I can tell, "lifestyle businesses" were not implied in the parent's comment... just "bootstrapping." There is plenty of room in between "lifestyle business" and "swing for the fences" -- your comment seems to imply that those are the only options.
The author edited the post since my response. I used the word lifestyle because that was the word he used.
There are a lot of options. Infinite options. There is also a big difference in potential risk and outcomes of those options. There is nothing wrong with approaches to creating lifestyle businesses. In many cases, this can be optimal.
