Technicians at NASA's Kennedy Space Center have attached the heat shield to the Artemis 2 Orion spacecraft, which will send astronauts around the moon for the first time in over fifty years.

A KINETIC ENERGY CONVERTER (KEC)
When material science improves, Starships returning to Earth will have a different heat dissipation. One that is efficient and simple.
My suggestion is an additional outer skin on each section. A ten mm clearance is required to house thousands of nine mm long radial spikes pointing inwards, thus magnifying heat dissipation.
Superheated steam can be ejected through external venturis to add thrust against the atmosphere. Heat tiles can be minimized because the best part is no part.

PS This KEC could be used on the Orion. Would someone do the mathematics? KE[1/2mv(2)] = Latent Heat of Super Heated Steam. This leads to kgs of water required to replace the heat tiles.
