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. :)

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.
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?
