SpaceX is all about getting the cost down. You are going to make a lot more travel and payloads viable by focusing on dropping the price to orbit by 10x or 100x or 1000x (about $20/kg is the goal for the in development superheavy rocket) than on optimizing for smoothness. For now it is smooth enough.
