Out of the box thinking, following, "The best part is no part. The best process is no process."<p>Parts eliminated: landing legs.
Process eliminated: Move Superheavy back to the launch pad.
td;lr<p>Existing SpaceX rockets land on legs.<p>For the SuperHeavy booster that will launch Starship, Elon wants to take the legs away and instead have it land on a platform intended to catch the rocket on its grid fins near the top.<p>This requires a very precise landing. But gets rid of a very heavy piece, and makes it easy to build a shock absorber. The downside is that you'll need to replace platforms any time one of these misses, hence the need for a <i>very</i> precise landing.<p>(The landing already has almost no margin of error given that they land with a suicide burn.)
