There are some people for whom growing a business is the exciting part. They can get excited about tax prep software if they see the opportunity.
I'm more like you (not one of those people). If I don't care about the problem, and (maybe more importantly) the users I'm solving it for, I won't solve it well.
Another point - not everything has to be a business - you can always work your day job and build adventure games on nights and weekends purely for fun.
Sometimes the best businesses come out of hobby projects. If not, whatever - it's fun and fulfilling.
I think most people want to run a business around something they really care about or are excited about, so when you have to run one around something you have zero interest in then I don't see the advantage anymore compared to taking a day job at some company.
