It is cheaper and easier and more convenient to use a wireless network.

Heh, you need to check your math, Chuckles. Cat 5e wiring costs almost
nothing nowadays...

You can then place computers anywhere you want, take your laptop out to
the yard, etc. There really is no unauthorized access problem any more,
most modern 802.11 AP/routers can be told to accept connections from
specific adapters only (you enter their hardware IDs).

Hate to tell you, but current wireless security is embarrassingly easy to
break. Hacking MAC access lists (what you're referring to) is trivial -
sniff out the address of any accepted adapter (found in the header of
every packet), and set your adapter to match. There are automated packages
out there to do it (and break WEP too, of course).

Just take your laptop and wireless card to any tech conference, and people
will gladly hack into it for you....

Now, obviously, true wireless security is possible; it simply hasn't made
a lot of market penetration yet.
