Then the business is not profitable enough to exist. Simple as that.
Then you can start thinking about real solutions to urban transit that have existed for more than a century.
It's a different unrelated group claiming that it shouldn't exist if it doesn't provide the pay / benefits they think it should.
And there are plenty that argue that under capitalism one isn't fully free. There is always the threat of losing the roof over your head.
The way I see it, it's already proven that riders will accept paying X dollars and drivers will work for X dollars, minus Y% for Uber's cut. Uber's Y% is likely higher than it needs to be, but at the end of the day, it's a SaaS app. Even municipalities have set up local competitors / clones.
These companies are certainly pouring a ton of money into expanding into new geographic areas, other business models, and more. But as long as riders will pay an amount even a little higher than what drivers will accept, it can be profitable.
See heavy drugs, prostitution and violence market as some examples where two consenting adults is not enough to form a legitimate business.
True: it is not the case that we should fundamentally allow any association between two consenting adults. No, this does not justify preventing it in other cases.
You can build a robust bus system, government run and not expected to make a profit, for example. You can have registered cabs. You can have rental bikes (bonus if they are electric assisted). If you can make sure scooters don't litter the walkways, that works as well. If you already have the infrastructure in place, perhaps trams or subways are a good thing.
We could expand busses to be able to travel from city to city. Same thing with trains: Make them run on time and expand. Busses, however, use the most extensive existing infrastructure and would likely be more cost-effective in most areas.
Not all "busses" need to be large, though. In some areas or at some times of day, a 15 passenger van might be enough. We could have bonus points if we changed school bus laws so that we don't have a duplicate bus system that leaves busses unused for much of the day.
In the US, one could take a sliver of the military budget (where there is plenty of waste) to pay for it.
Uber left Denmark after they decided that they have no interest in adhering to the relevant regulations. We still have trains, commuter trains, subways, busses, bikes, scooters, taxis and cars. People still can get to places and fairly conveniently.
