If we want no protections in business relationships, no special treatment, start with the very special protection/treatment/made up rule that is the fictional corporate 'entity'.
Or do some people (company owners) deserve special government labels/treatment/protections while others (zero hour workers) don't? If you don't want these rules, let's start at the start. No more corporate entities as they are just special protections and special protections in business are bad and create mis-incentives. Government shouldn't be in the business of giving people 'special protections' when it comes to business, right?
