Wireguard is great, I have personally donated to it and have used Wireguard for years before it became stable. And I still use it on devices (routers) where Tailscale is not supported. But as Jason stated - it is quite basic and is supposed to be used in other tools and this is what we are seeing with solutions like Tailscale.

Tailscale makes it simple for the user - no need to set up and maintain complex configurations, just install it, sign in with your SSO and it does everything for you. Amazing!

With Tailscale you don't have to learn anything, you just install apps and click.

One value of Tailscale for a ton of simple use-cases is that people don't have time / don't want to learn.

Even more trivial with Tailscale, so why wouldn’t I use Tailscale to configure wireguard for me?
