You asked what I would do, so I answered. :)

More seriously, the biggest barrier to laypeople coming up with practical solutions to this is that all of the forces involved are orders of magnitude outside of our experience. None of us has any intuitive concept of what things are like 5000 feet below the surface of the water. None of us has any idea what oil is like in that volume, let alone at that pressure and temperature.

I'd be more charitable about common sense solutions to the cleanup, since that seems like the type of thing we can have an intuition about. The bottom of the ocean however is an entirely alien environment, with (for all intents and purposes) different physics.

The only people with an intuition for this are the ones working on the solution professionally.
