This play baffles me. As well as the fact the Kirby only mentions the large knight's extension as an alternative. What is so great about the left side? White is already strong there. Black has no attack, and the remaining 2 space extension is small. In addition, what relation does this play have with Black's other stones?

is the obvious play, Not only is it a big point, it has a good relation to the marked stones.
People sometimes shrug off opening mistakes of this kind by saying that it only costs a point or two. But if you lost 2 points on every move you would get crushed. I would not be surprised if the difference between this play and the play in the game is more than two points.

For an alternative you might think of plays like this, to make it a bit easier to throw the tengen stone away. (Not that I recommend it, but it is better than the game play.)

Or if you want to extend from the bottom left corner, extend on the bottom side, where you have potential to develop.
Edit: Unhidden.
I don't understand this, exactly. Isn't it big for white to approach on the left? It seems that he can complement his influence well this way.
First, it is not a lot of influence, because of the bad aji. Second, you have a tengen stone. Weak though it is, it hinders White's influence.
Second, you have stones, too. How will you make them work together?
Third, as has been mentioned, the breadth of the bottom side is greater than the breadth of the left side.
Let's compare combs:

Suppose that Black plays on the bottom side and then White approaches from the left side. Play might continue this way. Indeed,
and
work well with
. But look how well
,
, and
work with
!
But, you may say,
and
are not territory oriented.
Sorry, you are the one who played a stone on tengen.
But, you may say, it was necessary to reduce White's framework.
Indeed, it was, and it would have been better to reduce it earlier, with the move Magicwand and I suggested.
----
I was reading something today about getting better at tournament chess. It suggested studying a few openings deeply, because there is a lot of declarative knowledge to learn, and you should specialize. That also works in go, but to a much lesser extent. The battlefield is larger in go, and the scope of the plays is more limited. Your opponent has much more leeway in go. You cannot steer the game so much into familiar territory.
Even though he was giving three stones, Magicwand created a position where your best play was to reduce. It does not matter that your game plan called for making territory. You missed an early chance, but later made an attempt with the play at tengen. (Not as good as a deeper play, but a good idea.) Now that you have made that play, how do you make your plays work with it? It doesn't matter what your original game plan was, you should make a framework with it. Well, you did not make a framework with it. Now how do you throw it away? Your next play ignores that question, as you secure a corner. (Which you later lose, anyway.) In the end you live with the tengen stone, for 2.5 points (!), while giving up a strong wall.
The observer has to wonder, What is Black doing?
It is one thing to play for territory. But if that is all your early plays do, they are losing points. Take a look at some ancient games, say, early 19th century. Play was more territory oriented than now. They did not have the whole board vision that developed in the late 19th and early 20th centuries. But they didn't just make territory. It is instructive to see how much they appreciated influence.
