Jet-A that has been combusted doesn't require any lift.

Edit: Since I have an aerospace engineering degree, I'll post the 100 level concept. https://web.mit.edu/16.unified/www/FALL/thermodynamics/notes...

But at the same time you had to design an aircraft to be able to shed that much weight and handle a load that sloshes around. That has cost. Again though, the core point is you can't compare directly. It is more about the final design and final purpose. eVTOL to NYC shows this. We may see quieter, less polluting cheap taxi service, basically a superior ability to function, because of being electric. If you only look for reasons it is worse, you will find them and not progress.
