Why should people care about all these things? Payments should be as straightforward as cash.

Agreed, that's why Phoenix tries to abstract pretty much everything away from the user. Maybe they could abstract even more things, but then since it's self custody there are things you **have** to tell the user. And when you charge them fees, users **want** to know how much and why. Seems to me that's the only two things Phoenix still explains in its interface.
