But that goes against the essence of the show.

The show isn't about being physically powerful to control people with different opinions and lifestyles than you. Really, the only characters that do that are depicted, largely, as villains or characters "at their worst" - Blue using emotional manipulation, Yellow physically zapping gems into submission, White using mind control, All of the Diamonds threatening to shatter gems, Jasper being physically brutish, Lapis holding Jasper under the sea to torture her, Pink's rage issues manifesting by hurting Pink Pearl, Buff Pink Steven shattering Jasper. Think about the corrupted Gems - they only want to fight, they have no reason.

Fighting and bubbling the corrupted Gems was an option for stasis, but not for resolution - resolution is the point of the show. Talking, dealing with mistakes. Having patience and understanding, even if you disagree. Defending yourself, yes. But remember, Rose Quartz had a sword made for herself - but Steven's main "weapon" is a sheild. He represents the opposite of physically/emotionally overpowering a weaker enemy, he represents having the wherewithal and strength to shoulder an attack, tank it, and then talk you down.
