There'd be no need to ban peer-to-peer networks - the payment method does not change anything. If there is an employer-employee relationship it'd break the law if they don't follow the regulations for such a relationship. If the drivers are genuinely small businesses, it wouldn't.
> So it's okay if they offer to work for a "slave wage" as a self-employed small business owner, but if they work through a third party, then it's not okay?
The implication is in part that the paperwork necessary to operate as a small business acts as a deterrent for people to enter into it without at least some degree of understanding of what they're entering into.
It is providing what you're arguing for (the ability to set whatever salary you want), but at the same time protecting society against some of the worst exploitation by providing some hoops you have to jump through.
> How it taking away an option in their interest? You're reducing the avenues through which they can sell their labour, which cannot possibly be to their advantage.
This is nonsensical. If I offer to pay you to work in conditions that are guaranteed to be lethal, according to your arguments it can't possibly be to their advantage, because I'm reducing the avenues through which they can sell their labour. Clearly reducing the avenues alone is insufficient to determine whether or not the decision is to their advantage.
> It worked incredibly well. Wages grew rapidly throughout the industrial revolution.
And through most of the period, worker activism grew rapidly as well. In a great many cases, workers died during actions taken to improve working conditions and salaries. The fantasy that those improvements are purely down to lack of regulation is just that. It took repeated bloodshed to bring about those improvements, and a lot of regulations that were often also paid for in blood.
If there is any takeaway from the growth in wages during the industrial revolution, it is that aggressive direct action by workers provides results.
