There's a pattern here: when an Elon Project is successful, he jumps in with Elon innovations, like cyber truck. The next example that will follow this pattern is building a rocket that's too big for orbital payloads, but takes 22 refueling flights to get beyond orbit.
What do you mean too big for orbital payloads? Mass to low earth orbit is what matters, which starship is well optimized for. You could always put a tiny third stage on there to go places, but that is back to the apollo style yeeting a tiny amount of mass somewhere else and would not help with getting serious tonnage to the moon and mars
