Why don't they make smart TVs/streaming devices with mouse controls?

I'm so annoyed with modern TVs. All of you probably know the story with using a streaming device/smart TV: super hard to use; too many buttons; trying to figure out how to use your friend's TV. Well, there seems to be a simple solution to all these problems: just use your TV with a mouse and trackpad. Oh, but wait, nobody makes TVs/streaming devices with mouse capabilities. Apple uses a trackpad on their remote, but it doesn't control a mouse, so why not just make that a trackpad that controls a pointer on the screen like computers do? Why don't they make TVs with mouse controls?

This is what I think a remote for a smart TV with mouse controls should look like. Why don't they do this? It's so simple?

As you can see, Apple's remote has a trackpad on the top of the remote, but unlike the trackpad you use on your laptop, it does not control a mouse.
