Why not just refloat the ship? Floats and weights in the right places, together with the tide going up and down ought to be able to turn it over. It wouldn't be too expensive either because all work could be done above the waterline at low tide.
When it's the right way up, industrial diesel powered pumps could pump it out enough to float and reuse.
Perhaps there were political reasons? (ie. if the ship is refloated, the original owner would own it, whereas if its scrapped the port authority can take the collected 'litter' as payment for the work)
Refloating was already tried a few times and failed
>PCTC Golden Ray was partially capsized in St. Simons Sound, Georgia, when the pilot deliberately grounded the 20,000-dwt ship in response to a fire on board on 8 September. It was sailing out with 4,200 vehicles on board and was grounded on a soft seabed.
>Attempts to refloat the vessel have so far failed and the US Unified Command handling the salvage has decided to disassemble the ship in situ. It believes attempting to right and refloat this ship would not be technically feasible.
The key to the salvage effort not involving refloating is probably related to the loose tangled masses of vehicles it's carrying; the ones that already caused the ship to fall over.
I don't think the original owner would own it outright, at the very least there is the Law of Salvage (https://en.wikipedia.org/wiki/Law_of_salvage) where the port authority (or whoever else refloated it) would be entitled to "a reward commensurate with the value of the property salved."
Also, from the first image in the picture you can see that the cargo has shifted and is now all on the side of the ship . Modern cargo vessels don't have that much excess stability, so chances are that it would not stay upright even if it were completely pumped full of air.
