I wouldn't say Elixir has more concepts, it is rather different concepts.

You also don't have to worry about performance and concurrency. I would actually argue that you have to worry less about performance and concurrency because you can go further without having to resort to cache layers, tuning, etc.

But ultimately, I don't disagree with you. If you are building CRUD apps, then any technology is likely fine. Perhaps there is a chance Phoenix will start to take a bigger pie of the "CRUD apps space" with LiveView (https://github.com/phoenixframework/phoenix_live_view). If you could produce CRUD apps at the pace you do today, but making them interactive and realtime is orders of magnitude simpler, would that interest you?
