i think you completely ignoring the main point i detailed out, that order matching is a tiny part of what uber does, is what is not in good faith. it's a company with 4 million workers in most countries and cities worldwide. let's say you want to start a taxi company in tokyo. find and hire about a thousand drivers. your costs are just writing an app, right? how about saudi arabia? now take those costs and multiply by 4000.

you want to compare to nyse? cool. ask them how much money it will take to trade every stock worldwide following local rules, for any country's citizen. hire 4 million workers. make sure i can use the same app for every transaction and just put it on my amex.
