Look at Coca Cola. They don't make anything that anybody else can't make.
Nonsense. I hardly even drink cola any more, but Pepsi still tastes like ass and Coca-Cola still tastes better. It's a complete falsehood to suggest that anyone else can do what Coca-Cola can do, because a lot of people have spent a lot of money trying and they've all failed so far. Coca-Cola doesn't have a good name just because they've had it for a long time, Pepsi is an old brand too. Coca-Cola has a good name because they make a product that people want to buy, and have been doing that for a long time. Even when they were busy dicking around with their recipes and alienating some customers they still managed to remain on top.
Uber, on the other hand, really can be replaced overnight, in whole or in part, in some cities or in all cities, in some countries or in all countries, etc. They do absolutely nothing that someone else couldn't do just as well, if not better.
So yeah, everyone else is being compared to Uber, you've got that right. And it's worth something, you've got that right, too. But comparing Uber to Coca-Cola is way off-base. I haven't consumed a cola that wasn't from a weird off-brand (Zevia, in this case) in literally years, but if I were going to get one in some mainstream establishment devoid of more potable choices like filtered water (you have to hand it to soda, they at least filter the water before using it, it's important for consistency) I would still lick the sweat off a dead dog's balls before I'd drink a Pepsi. I'd drink Tabasco. I'd drink mayo.
