Tailscale somehow found use for self-hosters, despite being wildly unergonomic for an all-Linux, non-corporate, network. Yggdrasil lacks marketing effort, but is otherwise a great option.
I can't tell if you're being sarcastic, but assuming you're not: Tailscale makes security easier because networks are private by default. To achieve a similar effect with Yggdrasil you'd have to use a firewall to whitelist the Yggdrasil IPs of all your devices. So it's more work to set up.
Huh? I thought one of the appeals of Tailscale is that security is done at the network level; plus that your network is private, so you don't get randos knocking at your ports.
Anyway; Tailscale is not your only network. If you’re on a laptop, you need to be able to log onto rando wifi networks. If you’re at home, you need to be mindful of your smart fridge going rogue. You need to run a firewall. Tailscale adds a separate, Tailscale-specific, firewall with centralized management. Now you have two firewalls.
