I don't think you've ever met Judaism, every single thing in it is carefully reasoned over. The [unprovable] "axioms" if you will, might not be ones you would pick, but given those axioms everything else flows logically.

Anyway,

A wall encloses a space. A wall can have doorways obviously, and still enclose a space.

What if you made the entire wall out of doorways?

And that's what an eruv is, it's a series of doorways all right next to each other. There are certain rules on how you construct an eruv, otherwise it's not considered a doorway, but rather an opening.

If that's "reasoning" then the Emperor's New Clothes are a three-piece suit made entirely out of buttonholes.

Pretty close but you aren't being nit picky enough.

What makes a button hole? It's not just the space, but also the frame of stitching that surrounds it.

So to use your analogy the suit would need to be made of many frames like that connected together.

What else makes a button hole? Well they are usually in a nice straight line, so you suit would have to be the same way, you could not have a messy pattern of random placement.

Keep going, what are the other essential elements of a button hole? Etc..

Take it to the full extreme, every element debated and defined and you would start to approach the way the thought process works.

(An eruv has a ton of very strict restrictions on its construction, otherwise it doesn't count. Superficially it seems simple, just a string, but actually getting all the details right takes a lot of effort.)

Bingo, now you're getting it.

Actually, I am Jewish, and I stand by my statement.
