Not possible at the moment. Without the large size, you can't fit an adequate battery to last a day or longer.
Not to mention that many people want good cameras on their phone, an they need space as well.
I'm typing this comment on a Zenfone 9, which is a pretty reasonably sized phone with a decent battery and camera. Charging to 80% usually lasts me over a day of usage. The camera is good enough as well. Phones don't have to be so massive to have those features
The Zenphone 9 has a bigger display than the "huge" pixel 4 from the video and is about the same size in each dimension.
It does have a pretty giant battery by comparison though.
