You seem to be arguing that, in balance, there are more low-paying jobs where the government can convince employers to increase wages, rather than the employers closing down and looking for another enterprise to pursue. Otherwise, even on aggregate, you are actively harming low-skilled or desperate workers who are looking for a job.

Let's assume, for argument's sake, that this is true - labor laws and protections increase wages in aggregate enough to account for all the jobs that are abandoned because they are not profitable enough to pay the required wages. There's one more thing to consider in Uber's case - the regional availability for jobs. Can we assume that the low-skilled adequate-income jobs you create through labor laws would be concentrated in richer towns, richer neighbourhoods, where the industry and market can afford the higher wages? What about the poorer neighbourhoods/towns? Uber(well, taxi service) allows people there to take a job which might not be available to them otherwise, without moving to a different town/neighbourhood.
