Realistic dApps

In the past, Vitalik Buterin once talked about how ETH could potentially replace Uber, in that it would connect the driver to a client directly with no middle man taking a chunk of the profits.

Is this even realistic with the current level of scalability on ETH with all of these L2 scaling solutions and the soon to come ETH 2.0 update? As in, could the blockchain handle such an application?

I’m all for this concept, it excites me, but one thing I can’t seem to wrap my head around is that who would build something like this when there would be no incentive since the middle man makes no money? I guess you could label it a non-profit for the sole sake of undercutting companies like Uber, but to me it still doesn’t seem feasible without out some incentive.

There is a blockchain version of Fiverr / Upwork called Braintrust (I’ve heard it’s catered to more professional work). This is a perfect example of what I’m talking about but it does indeed charge a 10% fee from what a freelancer would be paid but I believe it’s sortve done discreetly. I think it’s considered to be a ‘finders fee’.
