Wouldn’t it be more economical to install it in straight lines? I am sure there is a good reason but searching for it turns up nothing.

The stuff that is coiled is called “Concertina Wire’.
The reason for it being coiled, is because when you want to pick it up and move it, it collapses flat into rolls.
If it were straight, then it would have to be rolled up on spools.
But because it’s coiled, you can take a section and just squish it back together, tie it up on 2 sides, and you’re good to throw it on the hood of your truck or the back of your tank turret… With far less cuts/uniform-rips/etc than trying to wind the stuff up.
It’s also faster to get it laid out, because you can just stretch it out, as opposed to having to unwind.
