LANs are "layer 2 networks" - just because it's not a single piece of
layer 1 cable connecting all machines doesn't mean it's not a LAN.

The properties of a LAN ("every machine can talk to every other machine
*directly*, without having to go through a layer3 device") are quite
distinct from a "every machine has its own L3 subnet".

Addressing is explicitely *not* point-to-point in a switched L2 LAN,
which is still the most common way things are setup for things like
"employee office network" in most enterprises... - even if cabling might
be point-to-point.
