Any critical system daemons are 1024 and below. The reason the high ports are left open is for user applications to be able to communicate without users having to figure out the firewall.
Beyond the usual (HTTP, mail, DNS servers, etc), what is the average non-admin user going to set up that listens as a server? Admin-users setting up those traditional services ought to know how to manage firewalls, or they ought not to mess around with those services.
