Ok, got it.
So, this is my opinion.
Outbound rules (LAN -> WAN) make sense because they protect your lan devices from connecting to any of those "dangerous" IP.
Inbound rules (WAN -> LAN) are not needed unless you have a service in your lan listening (for example a webserver) and you wan´t to protect it from being contacted by those IPs.
As you said, by default, any inbound traffic coming into your router will be dropped unless there is an existing session or an explitit rule allowing it.
