While true, that can't be all that's wrong with it, because otherwise if you did this even once, turning all your mass to waste heat, you'd still have violated the First Law. It would still be more useless energy than you started with. Right?

Energy tends to become more useless, so I don't see how that's an argument against my point.

Energy tends to become more useless

This is true, and is an informal version of the second law of thermodynamics.

But this violates a different law, conservation of energy.

Even the highest entropy energy can still be used to do work, it's just not as efficient. I would predict that a team of engineers/physicists could exploit this to get free energy in the counter-factual universe where this is the only difference between our laws of physics.
