They can relatively easily sink it, and in fact are required to be able to in order to get their US FAA launch license. As part of the environmental assessment specifically, but I could be wrong on that. For those curious, they have recovery teams on sight who can essentially shoot it to further puncture the hull or attach explosives even. They have experience with their Starship boosters not sinking off the coast of Texas and floating into Mexican waters.
