After level 20 it is increasingly hard to catch even the usual 10cp pidgey. It is not uncommon to use up 5 or more balls (even great or ultra balls) to do it.
And yes, for some people it is important to 'catch them all'. There's not a lot of things you can do to gain XP, and XP requirements increase exponentially. Catching any pokemon for the 100th time (for candy or to evolve later) is a significant source of XP.
There is also no rhythm or reason as to why something like a pidgey takes so many and then other high cp things don't. I'm only level 14, but a pidgey can be a 5-10 ball event and then a high level cp is one.
