I disagree.
If RTLS and tower catch, then there is no need for landing gear.
Obviously Lunar or Mars ships will need them, but for Earth LEO the weight penalty for a landing gear that will never be used just doesn't make sense.

There really isn't much of a weight savings because it has to carry extra fuel for the landing maneuvers. I think it was a way to push the design of landing gear down the road. Ultimately it will have to be designed and built because of landing on unimproved surfaces.

Ultimately, nine raptors.

By the time Starship is manned, I'm confident there would be at least two launch towers at KSC, so landing/capture would not be the limiting factor.

Even if Booster could be shielded enough to withstand 4M+ lbs thrust of a full throttle hot stage, Starship still could not accelerate fast enough to escape with any real margin of safety.

Using 9x raptor 3 engines producing 538k lbs thrust each and the 2.9M lb weight of Starship (does not account for extra weight of the planned lengthening of Starship or the extra 3 engines) gives a thrust/weight of 1.66 providing 16.2 m/sec2 acceleration.  Super Draco's push Dragon at ~5.5Gs or 53 m/sec2.

Assuming instantaneous ignition, it would take Starship 3 sec to get 70m separation (one booster length) from Booster.

Either way, the fuel used for landing maneuvers will be needed whether the ship is landing on gear or caught on the tower - without gear, more fuel can be carried and it's one less failure point.
But I do agree that at some point landing gear will most certainly have to be designed into the ship - it just isn't needed now, or for quite a while imo.

In the future, most launches will be from Florida. So they're going to need a catch tower in the Azores.

Once they get the process down, they can station catch towers across the globe.  Elon can license Starship's base edition to countries that host, making them orbital powers when they launch from them.  Win win.

What happens with an abort situation?   If the only abort option is RTLS that could be problematic to having it man rated...which may be hard anyway.

Man rating is far down the list.
Dragon is already and is fairly cheap. The cargo and fuel launch demand for starship will always be huge compared to the bodies to space need.

I'm pretty sure that I read somewhere credible (NSF?) that it will be a lot easier to get approval just for HLS/space activities than full man rating with launch reentry landing. I'm not sure if it's the same terminology or what but that appears to be the plan. I think that's going to be a priority of the Polaris Program.

The only thing that makes this seem different is that the "lander" is the same architecture as a orbital launcher. They have always been so different that there was never a question.  No one bats an eye that the LEM was not rated to launch people into space from earth.

Hell, they could practically just throw a dragon in the nose if starship gets man rated as a launch vehicle first and meet the goals.

When Starship is ready for that job it’s going to be interesting to see if they can ever pull off that point to point airliner strategy they have proposed.

Regardless it is going to be awhile until accredited astronauts fly on it. Let alone whatever schlub can scrape together the $$$ for a ticket.

I've thought about that as a potential stopgap measure if they wanted to retire Falcon 9 before Starship was fully man rated.  
Dragon would need to be redesigned to incorporate TPS tiles that would just about completely cover it (including at least three of the super dracos and the docking hatch).
The second option would use an unmodified Crew Dragon capsule that would return separately from Ship.  Though in that case, they would have to modify Ship to survive reentry with the nose section missing where Dragon was.

Id guess that you dont want it too thick or you could end up with the top face being melted faster than the heat will conduct through the plate to the water.

There are more than a few obstacles to just using crew dragon on top of Starship.

-Limits crew size
-Requires the trunk (which adds another 10ft in length) for stability during escape and radiator/power while in orbit
-Would need addition of complete external heat shielding to survive reentry attached to starship
-Would have to detach in orbit and dock (with the docking port in the nose now covered with starship heat tiles) if Dragon capsule keeps it current heat shield

I know people have this idea of Starship being exactly what Elon says it's going to be and taking off and landing exactly according to his aspirational goal of catching them with a tower and turning them around in a matter of hours like a 747 but I'd never dismiss the possibility of certain things getting scaled back as development progresses.  

I think there's a real possibility that the final 1.0 production version of Starship lands on legs like a Falcon and without people on board but still changes the world profoundly by enabling a total payload to LEO and cost per kg that exceeds anything that we've ever seen.  That would be true even if Starship never launched and returned humans too.

Even if the booster and ship catching is ultimately deemed a bridge too far, the tower design still retains it's utility for stacking and launching as has already been demonstrated with the first test flight.

Now, that is a post.

It should be apparent by now, that a guiding philosophy of Elon endeavors, is robust design that allows for a backup sure thing plan for more risky initial plans.  The emphasis is on speed with a fail safe backup.

Carbon fiber was abandoned.  Not robust.   Not flexible.  Stainless steel was adopted.  Cryogenic.  The staple of significant chemical plant construction.

The concrete failed.  No big deal, austenitic stainless armor can be quickly constructed.
