It should be a rather obvious thing that it's sarcasm, and pointing out the
irony that by trying to type less you are only typing more. By trying to
save work you are only doing more work. And for what? Just to make the
actual code less readable.

The "using" statements there are not code per se. They don't do anything.
They only exist to make the code shorter later. In other words, they
exist for the goal of brevity-over-clarity.

Avoiding brevity-over-clarity is not about the total length of the code,
but about the readability of the code. There are many ways to make code
less readable, and one of them is to use names that are too short. The
goal of avoiding brevity-over-clarity is not to make the code longer,
but to make it more readable.

Your excessive use of 'using' isn't achieving that, but the opposite.

Have you ever thought there may be a good reason for it?

There are two types of people reading your code: You, and everybody else.
Unfortunately quite often the ease of understanding of the code is very
different for those two groups of people. (And, in fact, you yourself
will eventually become part of the latter group over the years, with
respect to code you write today. The more time passes, the less you'll
remember what you wrote and the more the (un)readability of your code
will start affecting even you yourself, if you ever come back to your
own code.)
