The state sets lower limits to what work should be worth, in order to avoid unpleasant social outcomes, such as worker abuse. It also sets a minimum of benefits companies should offer, in order to fulfil their side of the social contract - being allowed to safely do business and have access to capital, workers, etc.
If Uber, or any other company invents a type of work which cannot be compensated according to those rules, then they do not have a viable business and will go bankrupt or be fined out of existence.
In practice, they've managed to find enough loopholes to survive, while making the lives of many of their employees miserable.
Its abhorrent to me that you think the "social good" is a good enough reason to violate the rights of the individual. Access to food is a social good, but we don't say we should have the state provide universal access to food. We don't say that in housing. You could argue that access to technology is a social good, should the state be providing universal technology? Some people believe anyone with a skin colour that isn't white is adding to "unpleasant social outcomes.
My point really isn't that these things are or aren't social goods, but that the limits to social good and what it can be used to justify are far too vague and far reaching, ending up with the line being drawn only by the person who happens to be in charge at the time. Social good is the justifying call of tyrants.
I advocate for individual rights and property rights for everyone, allowing them to be free from the state using force. That includes the business men making decisions over their companies which is their property and their employees who choose whether or not they want to sell their labour to them.
