Why should I? I have a /64 network at home. Do you want to scan 2^64 IPs (18,446,744,073,709,551,616) to get the IP currently used by the laptop which is changed via the IPv6 privacy extension? The only machine having a fixed public IPv6 address, is the IPv6 Gateway. And this one has ip6tables :-)

And if you don't use that, I call that ignorant but mostly lazy security because it doesn't take a lot of work to type: "sudo ufw enable && sudo ufw default deny" and "sudo ufw allow <port>" unless you want to start to constrain it by tcp/udp and interface and even then it's not that complicated to type: "sudo ufw allow in on eth0 to any from any port <port> proto <proto>". What it does it mean when you don't even use the tools given to you that are easy?
