I tend to agree to this viewpoint. Most of the impactful products are built by people who are inspired to build the product, sometimes even to the extent of hating the entrepreneur. For them work is almost a part of life.I don't mean that such people think of work all the time and don't have other interests in life, but largely what they are building is kind of ingrained into their life. It's really difficult to separate what they do from who they are. Almost every leader wants their team to exhibit these characters albeit on a spectrum.

But what comes with that is the personality attributes, political viewpoints etc. It's hard to disagree on some fundamental traits and still continue to work together. At least in these teams which tend to get closely knit.

This could potentially lead to homogenous teams which we don't want.We want teams to hash out diverse and conflicting ideas. Really hard balance to achieve.
