So just close the ports (or more precise: Do not open them, as "closed" is the default for most software on Linux).

    Yup, and if some bad software wants to create malicious webserver they can not do it as all the ports that are open are used in a legit way. And thus can not really communicate either one or the other way.

    A webserver listens on port 80 or 443. Neither port can be claimed by a normal user (no port below 1024 can). But yes if you manage more than your own user on a desktop AND these other users are not allowed to start programs on their own THEN a firewall can be helpful; but this is not a normal situation for a desktop-client, isnโ€™t it?
