It's not always the case that bass is played that way, it is just the more traditional style.
If you check out Rufus Reid, he plays the whole bass.
Scott Lafaro played the whole bass, Gary Peacock, John Clayton, Christian McBride all play the whole bass.
Go get the Rabbath books (or work with him like Rufus also Ray Brown was interested in Rabbath and everything he could do to learn more about playing the bass) and a teacher that can help you learn to play the whole bass. Just remember music comes before technique. All your technique does is help you serve the music.
You also need a setup that allows you to play the whole bass and get a good sound. That was harder with high action and gut strings. I personally think Gut may work, but moderate string height off the fingerboard is a must.
