I've setup a Homelab recently and I'm quiet new to it so pardon my ignorance. I haven't exposed my Homelab to the internet (apparently) yet, therefore I'm using Tailscale for remote access, my question is what's the purpose of using Reverse Proxies (RP) like Nginx, Traefik etc. as in my understanding it exposes you (securely) to the internet, but still there are risks...

Everybody on YT and Reddit seems to use RP and I don't understand why, So is there a good reason to use it or should I just rely on Tailscale. Are there other benefits of using a RP I would like to get enlightened about Reverse Proxies... Thanks in Advance.
