Landing on the grid fins would be a really bad idea. Even though they're car-sized, they're not load bearing and "only" made of steel (not titanium etc. .. just yet). Starship's Raptors blast during hot staging is enough to bend them on the top. https://www.reddit.com/r/SpaceXLounge/comments/1g3bi7s/grid_...

Though the original plan was indeed to land it on the (reinforced?) grid fins: https://x.com/elonmusk/status/1344327757916868608

I actually think there is some old Starbase tour interview where a SpaceX guy implied it was Musk's idea, though I could be misremembering. Catching the booster kind of makes sense, since they needed the tower arms anyway for stacking and unstacking.

They need to be able to handle some forces but indeed likely not an equivalent of half or even quarter of the booster landing weight.
