I won't enumerate all the details why having one person have at least 51% voting power is valuable, because the writeups about stock shares does it better justice, but I will say that I think it's naive to think "we're best friends, that will never happen to us". At least one of the parties needs to be a big enough person to quickly recognize and change a relationship that is going downhill, because if the relationship is important, the current bad situation will lead to that resentment buildup, often times completely destroying any hope for a reconciliation. "We can't live together, so we don't" is a more useful state to be in than "We're friends, we should be able to live together."
