I agree and you are right for sole member LLC vs sole proprietorship - I was just against business partners based on past experience when responding to the poster for starting a new business with a partner.
Absolutely - I have to work hard to get these guys (almost always guys) who come in and say “We’re best friends forever, we’re going 50/50” to realize that somebody has to have the final say. I have tie-breaker language in those operating agreements that lets them designate 2 people who then pick one other person to help them make the decision.
