Some people value being able to see more of the content, especially if you're reading an article and not changing pages often. Want to see the bar? Take 1/10th of a second to scroll up slightly, and bam, the bar appears. Also, you can swipe from the edges of the screen to go back/forwards. Even simpler than tapping the arrows on the bar.
For the search bar? It's simple to clear it, can be used to type addresses as well as search, and prompts a simple to use sheet to select recent searches, bookmarks, websites, etc.
Not sure how having a differing opinion can make me "oblivious," as though you are God almighty and your opinion is the only one that's valid..
Notice how I never said you were wrong - just that your opinion isn't the only one.
