Not any reason except readability. I think you would need to have nested try catch blocks sometimes. I usually dont give the in the same try catch, but hide one of them in a function, just so it would look cleaner.

Not sometimes, but very often. The questions simply makes no sense and demonstrate some "mental anti-pattern". The whole way of thinking is wrong. I tried to answer, please see...

Using an idiotic code sample does not prove anything. For any valid and useful technique anyone can invent totally idiotic code sample using it, so what?

Nested try-catch blocks are important, that can be very useful, and there are many cases when they are just unavoidable. Besides, from the question, its not clear what do you mean by "nesting", just coding style or functional nesting. I mean, one can use several nested "try" statements in the same method, or inner "try" statements can be carried out of one method into a separate method, which usually improve readability (but even that is not a must).

Now, I don't want to explain any reasons for exception uses, because it's boring and very obvious thing. Why doing that if the whole approach is wrong and the question makes no sense, because the question is based on the assumption that nesting "try-…" blocks are bad.
