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.
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread is at almost 500 questions in about a month, so I think it's time for a new one.
Also, I have a new "stupid" question.
