That’s weird, I get windchimes

Linux with no services? That’s not a usable system for anyone who would ask “do I need a firewall”

Systemd is a service that runs logind. What are you doing without them?

That’s a bad mentally as well. Most stacks these days are about quantity not quality. If you blindly hit 10000 targets it’s more profitable than trying to spear a single one.

Akin to not wearing a seatbelt because you are unlikely to be killed by a sniper

You shouldn’t trust your device. Modern software is insanely complicated, even netbsd had an rce.

No you aren’t, browser based malware puts the attacker inside your fancy network. A basic firewall will greatly hinder any attack at basically no cost to you.

There is no reason to not leverage a firewall. Plenty of browser based malware can breach your home router and call back out to allow an attacker to explore your network. Windows has included a firewall for over a decade and it’s fine. You can with a single command enable Linux’s built in firewall and be glad you did the bare minimum of cyber security.
