No it doesn't.

If I have a massive copper block, heat insulated that requires a significant amount of energy to get to operating temperature every time I use it, but requires very little to keep it at temperature, doesn’t reheating it have the potential to use more energy if you’re planning to use it in short succession? Your statement implies I should always turn it off regardless of time interval.

I’m not getting this blanket statement reply.

Keeping something above room temperature will always use more energy than letting it cool down and heating it back up when needed

Sounds like the LLM you used when writing this slop comment struggled with the problem too. :>
