Do I really need a firewall for my server? (sopuli.xyz)

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?

That depends. If you have exposed services, you could use some features of the firewall to geoip restrict incoming requests to prevent spam from China and Russia and whatnot.

If you don't have any services running on a publicly accessible port, then what would the firewall protect?
