comment Why does iptables accept packets on a given port, when it is closed?
Well it is a risk. Because it's not dropping it like packets on other ports, an attacker can deduce that there may be something listening there in future, and continue periodically checking whether there is yet. If all other ports are blocked, then checking this one reveals that you exist at all.
