It makes as much sense as all the other "get arounds" that exist in most
religions

The one I like is the eruv.

I once heard of an eruv where the wired off area was very small....but
that was considered the 'outside'....


You just don't understand the finer points of religious reasoning. An
eruv is a boundary wall taken to its most minimal extreme. You start off
by asking what a wall is, and move on to asking whether it's still a
wall if it's not in good condition. Everybody would agree it is. Then,
what if it has holes in? Sure, that's okay. So, what if the holes are
really big holes? That's okay, too. So, you end up with an eruv, which
is a wall with a simply huge hole in it.

It's all perfectly logical, but if you think of it as a boundary marker
you may be happier. It's no different, really, from the boundary line
between neighbouring counties, but even that tenuous line acts as a
barrier to policemen.
