Really? I live in Barcelona and there are always taxis ready for the hailing :) Uber and Lyft are not common here, though a local alternative, Cabify is. But whenever I use cabify I need to wait for ages for them to get there, and tens of taxis pass me during this time. So I only use them when I want the quiet of a nice car or when I want to know how much I'll pay in advance.

There are still some payphones here too, but most of them have been vandalised, that's true.
