The point is that Industrial Revolution capitalists used the same argument that you're using. Those people were "freely" working, except that it was the only real work that could be had. Are people working for Uber/Lyft for whom it's the only way to feed their families, or to supplement their income enough to pay the mortgage or make the rent still "freely" working? If everyone had secure salaries with healthcare and vacation days, how many of those people would "freely" choose to continue working for Uber and Lyft?
People freely worked under abusive conditions in factories in the Industrial Revolution before the labour rights movement. No one wants to go back to that.
