That is the point of the law. If you want to work exclusively for one company, you are not a freelancer- you are an employee and the company owes employer taxes for you. They don't get off and you don't get to ask for relief for them using the "they will terminate my contract". If that is allowed, every industry will find a way to start using freelancers instead of employees. Which is fine if you so desire, but then you have to re-jig how taxes like social security, unemployment insurance and workers comp are collected and worker protections like min wages and overtime are enforced. Else you are just allowing for a few tax dodgers from benefiting at the expense of everyone else.
You are misinformed. Freelancers pay the exact same social security, Medicare and other taxes as employees. The bookkeeping is slightly different, but the amount collected is identical.
