It might not be that simple - I've read an article how they recovered one of the solid rocket boosters from the first successful Ariane 5 flight to check all was fine. IIRC it was a slog, they had to tow it back very very slowly, avoid it sinking, fighting all kinds of weather and tow line issues, etc. Have not found the article, but there is a picture how it looked like[0].

With Starship it could have been similar & possibly worse given the size and more complex shape (various voids that might fill/drain & the thing is not really built for floating). Also you are in the middle of an ocean (Indian in this case) with potential for all kinds of weather on the way. Towing might again be very slow, so you might need to stage a massive submersible transport ship or something similar to make a recovery successful. And then the thing might still tip over and explode anyway - meaning all this was in vain.

I think is most likely they won't bother and instead just stream as much data as possible over Starlink in real time (or heck, even via WiFi once the buoy is in range) for analysis. They want to catch the shop eventually anyway, so manual post flight analysis will wait.

They can now check all over the first recovered booster anyway. :)

But, couldn't they wait for like, 6 hours? Take a good look when it's cooled down a bit. Send some drones over to film it, and then sink it?

I get that towing is probably too expensive for what it's worth. But I'm surprised they don't even go pick up some tiles before kablooing it.

Attach a tether to one of the fin pods, then blow up the rest to sink it cleanly and bring back the important part.
You wouldn't need to tow it; if you really wanted to you could use one of those deep see platform recovery ships that sink themselves. The rocket is big but it's tiny compared to ocean-going vessels.
Possible yes but still, this is a prototype with new fin configuration, materials and lots of detail to be understood from inspecting it in detail. An inspection would be very useful.

At the same time, this is SpaceX and they have a few others ready to launch already. Perhaps they indeed can keep it somewhat coarse and wait for detailed inspection until one of them makes it right back to solid ground?
