Peter,
This isn't a silly question. This question gets asked almost daily, and should
be asked more.
If you have multiple computers on a LAN, and any one of them is used for
Internet access of any type, you should have a personal firewall on each one of
them. If any one of them should get infected, it could be with a combined
threat that enters the LAN as browser data, and then attacks other computers on
the LAN. Having a PFW on each one could save the others, and could alert you to
the infection.

The broadband tech needs to educate himself a bit more. Why do you think that
there's no requirement for inter-PC protection?
