I argued it isn't rude because it is part of your purchase, not because it is legal.

Part of the purchase as defined by the contract, not common courtesy.

Contracts are legal devices, but they correspond to agreements between humans that have moral meaning. I am entering into an agreement with the driver when I book and Uber, and the terms of our (moral) agreement are reflected in the legal contract. It's not rude to take advantage of something you've bought.

You've succinctly distilled the differences informing our perspectives - in my opinion, the contract sets the floor: following the letter of the law (or contract) is necessary, but not sufficient for common human decency. YMMV.

I don't claim that contracts or law are either necessary or sufficient for common human decency.
