Sure it does.  A typical home network these days uses ethernet switches,
rather than hubs.  The switches are smart, they memorize MAC addresses
and then send traffic only where it needs to go, keeping other ports
free for their own traffic.

Multicast defeats that, sending all (multicast) traffic to all ports
all of the time.  Much, much heavier network load.

Probably still not a big issue, but the original poster makes a good point.
